How to Design, Manufacture and Customize Two-Sided Challenge Coins for Military Units, Police Departments, Firefighters, Corporations and Organizations
A double-sided challenge coin gives you two faces to tell one story.
One side can present a unit insignia, company logo or organizational emblem, while the other can carry a mission statement, commemorative date, achievement, historical symbol or personalized message. This makes double-sided challenge coins particularly useful when a single design cannot communicate everything on one surface.
But designing a successful two-sided coin is not as simple as putting two separate images onto a metal disc.
The front and back need to work together in terms of scale, relief, lettering, borders, enamel, plating, thickness and overall visual balance. The manufacturing process also needs to account for both sides from the beginning.
At ChallengeCoinBadges, we manufacture custom metal products including challenge coins, medals, police badges, military badges, lapel pins and other insignia. Our experience in custom metal manufacturing allows us to look at a challenge coin from both sides: how it should look to the customer and how it needs to be engineered for production.
This guide explains how to design a double-sided challenge coin, what manufacturing decisions matter most, common mistakes to avoid, and several practical design case studies.
What Are Custom Double-Sided Challenge Coins?
A custom double-sided challenge coin is a metal coin featuring a separately designed front and back.
The two sides can be:
- Completely different
- Visually related
- Based on the same central emblem
- One side logo-focused and one side text-focused
- Both 2D
- Both 3D
- A combination of 2D and 3D elements
- Different colors or finishes on each side
The important advantage is simple:
You have two surfaces to communicate your organization’s identity and story.
For example:
Front
Department badge + organization name
Back
Mission statement + establishment year + commemorative message
This approach is particularly effective for military units, police departments, fire departments, veteran organizations and anniversary programs.
Commercial manufacturers commonly offer different artwork on each face, while some also support 3D sculpting, dual plating, decorative borders and different enamel techniques.
Why Choose a Double-Sided Challenge Coin?
The biggest advantage is not simply having “more space.”
It is having more storytelling capacity.
A well-designed two-sided coin can separate information according to importance.
For example:
| Front Side | Back Side |
|---|---|
| Unit insignia | Unit history |
| Company logo | Company mission |
| Police badge | Department motto |
| Fire department emblem | Firefighter memorial |
| Event logo | Event date |
| Anniversary emblem | Historical information |
| Organization logo | Member recognition |
This prevents the front side from becoming overloaded.
Instead of trying to put ten different pieces of information onto one surface, the designer can create two complementary compositions.
Double-Sided Does Not Mean Two Unrelated Designs
One of the most important design principles is visual continuity.
The front and back should feel like they belong to the same coin.
They do not need to look identical, but they should share some visual language.
This can be achieved through:
- Matching borders
- Consistent typography
- Similar line thickness
- Related plating
- Complementary colors
- Similar relief depth
- Repeated symbols
- Consistent design proportions
For example, a military challenge coin might use:
Front: Eagle + unit insignia
Back: American flag + unit motto
The artwork is different, but both sides use the same antique gold finish and rope-cut border.
The result feels like one professionally designed object rather than two unrelated graphics.
Popular Double-Sided Challenge Coin Design Ideas
1. Military Unit Challenge Coins
Military organizations are one of the strongest applications for double-sided coins.
A common structure is:
Front
- Unit emblem
- Unit number
- Branch insignia
- Eagle
- Shield
- Aircraft
- Vehicle
- Symbolic mascot
Back
- Unit motto
- Mission statement
- Deployment information
- Establishment date
- Location
- Campaign reference
- Memorial information
For highly detailed military artwork, 3D relief can add depth to aircraft, vehicles, people, buildings and insignia. Manufacturers commonly use 3D sculpting when the customer wants dimensional details rather than a flat graphic appearance.
2. Police Challenge Coins
Police departments often use the front of a coin to emphasize the department identity.
Front
Police badge + department name
Back
Motto + city + year established
Another option is to use the second side to recognize a particular division:
- SWAT
- K-9
- Traffic Division
- Special Investigations
- Training Division
- Honor Guard
A dark metal finish, antique silver or dual-plating approach can work particularly well with police insignia, especially when the design contains substantial raised metal detail.
3. Firefighter Challenge Coins
Firefighter coins provide many opportunities for symbolic design.
Possible front-side elements include:
- Maltese cross
- Fire helmet
- Fire truck
- Fire station
- Fire axe
- Department badge
The reverse could feature:
- “To Serve & Protect”
- Department history
- Station number
- Memorial dates
- Firefighter recognition
- Event information
Red enamel combined with gold, silver or antique metal can create strong visual contrast.
4. Corporate Challenge Coins
Challenge coins are no longer limited to military and first-responder organizations.
Companies can use double-sided coins for:
- Employee recognition
- Years-of-service awards
- Leadership programs
- Corporate anniversaries
- Product launches
- Team-building events
- Sales achievements
- Customer appreciation
For a corporate coin, a clean design is often more effective than an excessively detailed one.
Example
Front: Company logo + 25th Anniversary
Back: “25 Years of Innovation” + founding year + current year
The two sides together communicate both the brand and the milestone.
5. Commemorative Challenge Coins
A double-sided coin is particularly suitable for historical or commemorative projects.
One side can represent the event.
The other side can preserve the story.
For example:
Front: Memorial emblem
Back: Name + date + short message
This creates a physical keepsake rather than simply a promotional product.
6. World Cup, Sports and Event Coins
Large sporting events and international events can also benefit from double-sided designs.
One side might feature:
- Event logo
- Trophy
- Mascot
- Stadium
The reverse can contain:
- Host city
- Event date
- Country symbols
- Team-related artwork
- Commemorative wording
For complex event designs, the designer should prioritize the main visual element and avoid filling every available area with text.
7. 2D vs. 3D Double-Sided Challenge Coins
Both 2D and 3D designs can work well.
2D Double-Sided Coins
2D coins generally use raised and recessed areas with relatively flat artwork.
They are suitable for:
- Logos
- Text
- Simple symbols
- Corporate designs
- Organizational emblems
3D Double-Sided Coins
3D coins use multiple relief levels to create greater depth.
They are particularly effective for:
- Human portraits
- Animals
- Vehicles
- Aircraft
- Buildings
- Landscapes
- Complex insignia
However, more detail is not automatically better.
A 3D design must still maintain sufficient separation between important elements.
The objective is not to put the maximum amount of detail into the mold.
The objective is to create detail that remains visible at the finished coin’s actual size.
How to Design a Double-Sided Challenge Coin
Step 1: Define the Purpose
Before drawing anything, answer one question:
Why are you making this coin?
Is it for:
- Recognition?
- Membership?
- Military tradition?
- A retirement?
- An anniversary?
- A memorial?
- Corporate branding?
- An event?
The purpose should influence the visual direction.
A retirement coin may feel personal and commemorative.
A corporate recognition coin may need to feel cleaner and more premium.
A military unit coin may prioritize insignia and symbolism.
Step 2: Decide What Belongs on Each Side
Do not simply divide the artwork randomly.
Create an information hierarchy.
Strong structure
Front = identity
Back = story
For example:
Front:
POLICE DEPARTMENT
BADGE / EMBLEM
Back:
SERVICE • HONOR • COURAGE
EST. 1986
This is easier to understand than putting every piece of information on both sides.
Step 3: Choose the Coin Shape
Round coins remain the classic choice, but custom shapes can provide stronger branding.
Possible shapes include:
- Round
- Shield
- Star
- Cross
- Badge
- State outline
- Vehicle silhouette
- Organization-specific shape
Custom coin suppliers commonly support both traditional round formats and custom outlines.
However, unusual shapes can make the design more difficult to balance.
The shape should support the artwork rather than become a distraction.
Step 4: Select the Size and Thickness
Size affects how much information can be comfortably displayed.
A design with:
- Small text
- Detailed artwork
- Multiple borders
- 3D relief
may require a larger diameter than a simple logo coin.
Many commercial custom-coin specifications use sizes around the 1.5–2 inch range, while larger formats are also available. Exact specifications vary by manufacturer and design.
Do not choose the coin size only according to price.
Choose it according to the amount of information that needs to remain readable.
Step 5: Select the Metal and Plating
Common metal and plating choices include:
- Gold
- Silver
- Antique gold
- Antique silver
- Black nickel
- Bronze
- Copper
- Dual plating
Polished finishes provide stronger reflection, while antique and matte finishes can create additional contrast between raised and recessed areas.
Dual plating can be particularly useful when the design contains two important visual layers.
Step 6: Decide Between Soft Enamel and Hard Enamel
Soft Enamel
Soft enamel sits within recessed areas and leaves the metal borders raised.
It creates a tactile appearance and works well for many organizational and military-style coins.
Hard Enamel
Hard enamel is filled to a smooth surface and creates a cleaner, flatter appearance.
It can be a good option for corporate and premium designs.
The important point is not that one is universally superior.
The choice should depend on the artwork, desired appearance and budget.
Step 7: Engineer the Relief
This is where the design moves from graphic artwork to manufacturing.
The manufacturer needs to consider:
- Raised areas
- Recessed areas
- Relief depth
- Fine lines
- Text
- Borders
- Enamel channels
- Edge structure
A computer rendering can look excellent while still requiring changes before mold production.
That is why experienced manufacturers review the artwork for manufacturability instead of simply reproducing the image.
Step 8: Create the Digital Proof
A professional proof should show:
- Front
- Back
- Size
- Plating
- Colors
- Relief
- Border
- Special features
For double-sided coins, both faces should be reviewed together.
The front might look perfect individually but clash with the reverse when both sides are considered as one product.
Digital visualization and production records are commonly used to evaluate both sides before physical production.
Custom Double-Sided Challenge Coin Manufacturing Process
At ChallengeCoinBadges, a typical custom project can be approached through the following stages.
1. Concept and Artwork
The customer provides:
- Logo
- Sketch
- Existing badge
- AI/PDF/vector artwork
- Reference photos
- Text
- Color requirements
If the artwork is incomplete, the design team can help develop it into a production-ready concept.
2. Engineering and Mold Preparation
The approved artwork is converted into manufacturing geometry.
For a double-sided coin, both faces need to be engineered.
This is especially important when the design contains:
- 3D relief
- Fine lettering
- Deep recessed areas
- Multiple borders
- Complex symbols
The production mold must accurately reproduce the intended relief.
3. Metal Forming / Die Casting
Depending on the selected material and construction, the coin can be produced using processes such as die striking or zinc-alloy die casting.
The manufacturing method should match:
- Shape
- Relief
- Quantity
- Material
- Design complexity
4. Surface Finishing
After forming, the coin can receive its selected surface treatment.
Possible finishes include:
- Polished gold
- Antique gold
- Polished silver
- Antique silver
- Black nickel
- Matte
- Dual plating
Surface treatment is important because it changes how the relief and details are perceived.
5. Enamel Filling
If the design includes color, enamel is applied to designated recessed areas.
The production team needs to control:
- Color consistency
- Filling level
- Edges
- Overflow
- Surface cleanliness
For a double-sided coin, both faces need to be inspected independently.
6. Polishing and Final Surface Treatment
Selected raised metal areas can be polished to create contrast against antique or matte recessed areas.
This is particularly effective for 3D coins.
7. Quality Inspection
The final inspection should evaluate:
- Coin dimensions
- Thickness
- Plating consistency
- Enamel quality
- Surface defects
- Text clarity
- Relief definition
- Edge quality
- Front/back consistency
A professional quality-control process should consider the coin as a finished product rather than checking only whether the artwork looks approximately correct.
Study Case 1: Military Unit Double-Sided Challenge Coin
Customer Requirement
A military unit needs a commemorative coin for members completing a major deployment.
The customer wants:
Front
- Unit insignia
- Eagle
- Unit number
- 3D relief
Back
- Deployment location
- Dates
- Unit motto
- American-themed symbolism
Initial Design Problem
The first artwork contains too much text on the reverse.
The coin is only around the size of a typical pocket challenge coin.
When reduced to the intended production size, several lines of text become visually crowded.
Manufacturing Solution
Instead of reducing the text excessively, the design is reorganized.
The front becomes primarily visual.
The back uses:
- Larger typography
- Fewer words
- More negative space
- A simpler background
The manufacturer also recommends an antique metal finish to emphasize the 3D relief.
Final Design Principle
Remove information before reducing important text to an unreadable size.
This is a very important rule in small-format metal manufacturing.
Study Case 2: Police Department Challenge Coin
Customer Requirement
A police department wants a coin to recognize officers completing a specialized training program.
Front
- Department badge
- “POLICE”
- Department name
Back
- Training unit emblem
- “Excellence in Service”
- Training year
Design Challenge
The department badge contains many fine details.
A completely flat 2D design makes the badge appear visually dense.
Solution
The central badge is converted into controlled 3D relief.
The background is kept simpler.
The border uses a contrasting metal finish.
Blue enamel is used selectively rather than filling the entire coin.
Result
The finished coin has a clear hierarchy:
Badge → Department → Recognition message
Instead of trying to make every detail equally prominent, the design gives each element a specific role.
Study Case 3: Corporate 25th Anniversary Coin
Customer Requirement
A technology company wants a premium employee recognition coin.
Front
Company logo + “25 Years”
Back
“Building the Future Together” + founding year + current year
Design Direction
Unlike a military coin, the company does not need extensive 3D sculpting.
The design is intentionally clean.
The manufacturer recommends:
- Polished silver
- Selective matte areas
- Hard enamel
- Minimal border decoration
Why?
The company’s brand identity is modern and minimalist.
Adding excessive relief would not necessarily improve the design.
Lesson
Manufacturing complexity should serve the design—not replace it.
10 Design Mistakes to Avoid
Mistake 1: Putting Too Much Text on Both Sides
A coin is not a brochure.
If you need a paragraph of information, the coin may not be the right medium for it.
Use short phrases, dates, names and meaningful words.
Mistake 2: Making Every Element 3D
3D relief is powerful when used strategically.
If every component is heavily sculpted, the visual hierarchy can disappear.
Mistake 3: Ignoring the Reverse Side
The back should not be treated as an afterthought.
It is half of the product.
Mistake 4: Using Too Many Colors
More colors can make a coin more colorful, but not necessarily more professional.
A controlled palette usually produces a stronger result.
Mistake 5: Designing Only for the Computer Screen
A coin viewed at 500% zoom on a monitor is not the same as a 40–50 mm metal object in someone’s hand.
Always evaluate the actual production size.
Mistake 6: Approving a Design Without Checking Manufacturing Details
Before mold production, verify:
- Size
- Thickness
- Plating
- Enamel
- Relief
- Border
- Edge
- Text
- Front/back orientation
This prevents expensive corrections later.
How Much Does a Double-Sided Challenge Coin Cost?
There is no universal price.
The final cost depends on several variables:
Quantity + size + thickness + material + mold complexity + relief + enamel + plating + special features + packaging + shipping
Double-sided coins may require tooling for both faces, depending on the manufacturing method and supplier. Some manufacturers explicitly describe separate tooling for the two sides.
A more complicated 3D double-sided coin will generally require more engineering than a simple flat design.
For this reason, requesting a quote based only on “1.75-inch double-sided coin” is not enough.
A manufacturer should normally review the artwork before giving a final production quotation.
How to Reduce the Cost Without Making the Coin Look Cheap
If your budget is limited, do not immediately reduce the metal thickness or eliminate important design elements.
Consider:
1. Simplify the artwork
Remove unnecessary micro-details.
2. Reduce unnecessary colors
Use a controlled color palette.
3. Use 2D instead of full 3D where appropriate
Not every element requires sculpted relief.
4. Increase the order quantity
Larger quantities can reduce the average cost because tooling and setup expenses are distributed across more units.
5. Keep the shape practical
Highly complicated outlines can increase manufacturing complexity.
6. Avoid unnecessary special features
Spinning parts, cut-outs and additional components can increase production complexity.
What Makes a Reliable Challenge Coin Manufacturer?
When buying custom double-sided challenge coins, price should not be the only consideration.
Experience
Look for a manufacturer with real experience in custom metal manufacturing rather than simply a reseller displaying stock product images.
Expertise
The supplier should be able to explain:
- Why a particular finish is recommended
- Whether the text is manufacturable
- Whether the relief is sufficient
- Which enamel process fits the design
- Whether the proposed shape is practical
Evidence
Ask to see:
- Similar completed projects
- Production samples
- 2D/3D examples
- Finish examples
- Manufacturing photos
- Quality-control procedures
Trust
A professional supplier should tell you when an idea needs modification.
That is more valuable than a supplier who says “everything is possible” and only discovers production problems after the order has been placed.

FAQ: Custom Double-Sided Challenge Coins
Can both sides have completely different designs?
Yes. A double-sided coin can use different artwork on the front and back. This is one of its main advantages.
Can both sides be 3D?
Yes, depending on the design, size and manufacturing method. However, the relief should be engineered carefully so that both sides retain clear visual detail.
Can I use different colors on each side?
Yes. Enamel can be applied independently to different areas on each side.
Can I use different finishes on each side?
Depending on the manufacturing specification, different plating or surface effects can be incorporated. Dual plating is also available for designs that require multiple metallic appearances.
What is the best size for a double-sided challenge coin?
There is no universal best size. A simple logo may work well on a smaller coin, while detailed artwork and small text may require a larger diameter.
How thick should a challenge coin be?
Thickness depends on the desired weight, relief, design and manufacturing process. Standard specifications vary among manufacturers, so the correct thickness should be selected according to the artwork and intended use.
Is a 2D or 3D coin better?
Neither is automatically better.
Choose 2D when you want a clean, straightforward design.
Choose 3D when dimensional relief is important to the visual concept.
Can you make custom-shaped double-sided coins?
Yes. Custom shapes such as shields, badges, stars and organization-specific silhouettes can be engineered depending on the design.
Can I put text around the edge?
Yes. Edge engraving and decorative edge treatments are available on many custom coin specifications.
Can I add a serial number?
Sequential numbering can be incorporated into suitable designs and production methods. Some custom coin manufacturers offer sequential numbering as an additional feature.
Can I order a double-sided challenge coin with a logo?
Yes. Customers can provide a company logo, military insignia, police badge, organization emblem or other artwork as the starting point for a custom design.
What file should I send?
Vector artwork such as AI, EPS, SVG or PDF is generally preferable because it allows the manufacturer to work with clean lines and scalable artwork. Raster images can also be used as references when vector artwork is unavailable.
Should I approve a proof before manufacturing?
Absolutely. The proof should show both sides and should be checked for text, colors, plating, proportions, relief and other production details before mold production begins.
How long does manufacturing take?
Production time varies according to the manufacturer, quantity, design complexity, tooling, finishing and shipping method. Do not rely on a generic lead time until the specific project has been reviewed.
Final Thoughts
A great double-sided challenge coin is not simply a coin with artwork on both sides.
It is a small piece of metal that has to communicate identity, history, achievement and emotion within a very limited physical space.
The strongest designs usually follow a simple principle:
Front = recognition.
Back = story.
From there, the manufacturer needs to balance:
Artwork → Size → Relief → Enamel → Plating → Manufacturing → Quality Control
When those elements are designed together, a double-sided challenge coin can become much more than a promotional item. It can become a meaningful symbol that people keep, carry and remember.
