Custom Challenge Coin, Medal, Police Badge, Military Badge, Metal Badge, Lapel Pin & Keyring Design Guide

Designing a custom challenge coin, medal, police badge, military badge, metal badge, lapel pin, or keyring is more than putting a logo on a piece of metal.

A good design needs to balance visual impact, manufacturing limitations, readability, durability, cost, and the intended application.

A design that looks excellent on a computer screen may become difficult to manufacture when it is reduced to 25 mm, 40 mm, or 50 mm. Small text may disappear, narrow metal lines may become too fragile, and complicated artwork can increase tooling and finishing costs.

This guide explains how to prepare artwork that is attractive, manufacturable, and suitable for professional OEM production.


1. Start With the Purpose of the Product

Before designing the artwork, define what the product is supposed to accomplish.

Challenge Coins

Common applications include:

  • Military recognition
  • Police recognition
  • Firefighter organizations
  • Corporate awards
  • Anniversary events
  • Clubs and associations
  • Commemorative events
  • Promotional campaigns

A challenge coin should usually have a strong central symbol that can be recognized quickly.

Medals

Medals are commonly used for:

  • Running events
  • Marathons
  • Soccer tournaments
  • School competitions
  • Corporate awards
  • Military recognition
  • Anniversary celebrations

The design should be visually strong from a distance because medals are often photographed after an event.

Police & Military Badges

These products generally emphasize:

  • Identity
  • Rank
  • Unit
  • Organization
  • Symbolism
  • Authority
  • Heritage

The design needs to maintain clear hierarchy between the main emblem, text, numbers, and decorative elements.

Lapel Pins

Lapel pins are usually smaller, so simplicity becomes more important.

Keyrings

Keyrings need to balance appearance with functionality because they are frequently handled, carried, and exposed to friction.


2. Choose the Right Product Size Before Finalizing Artwork

One of the biggest design mistakes is creating the artwork first and deciding the size later.

The size should be established at the beginning.

Typical dimensions might include:

ProductCommon Size Range
Challenge Coin30–60 mm
Medal40–80+ mm
Police Badge50–80+ mm
Military Badge25–70 mm
Metal Badge20–70 mm
Lapel Pin15–40 mm
Keyring30–60 mm

These are general design ranges rather than fixed industry standards.

A 25 mm lapel pin has much less space for detail than a 60 mm challenge coin.


3. Design for the Actual Production Size

A logo that looks perfect on a 4K monitor may not work at 30 mm.

Always check the artwork at its actual physical size.

For example:

On Screen

A company name may look perfectly readable.

On a 25 mm Pin

The same lettering may become too small to reproduce clearly.

This is why professional manufacturers often recommend simplifying artwork before tooling.


4. Keep Text Large Enough to Read

Text is one of the most difficult elements in small metal products.

Avoid:

  • Extremely thin fonts
  • Very narrow lettering
  • Excessive text
  • Long sentences
  • Tiny dates
  • Complicated decorative fonts

Instead use:

  • Bold lettering
  • Short phrases
  • Strong contrast
  • Clear spacing
  • Simple fonts

For a challenge coin, for example:

UNIT • HONOR • SERVICE

may work better than placing a long paragraph around the entire edge.


5. Create a Strong Visual Hierarchy

Good designs normally have three levels:

Primary Element

The main logo, emblem, animal, building, person, or symbol.

Secondary Element

Unit name, organization, event name, or slogan.

Supporting Details

Date, location, rank, number, motto, or decorative elements.

This hierarchy prevents the product from becoming visually crowded.


6. Challenge Coin Design Guide

A challenge coin often has two sides.

This gives you much more design space than a small lapel pin.

Front Side

Consider using:

  • Main emblem
  • Organization logo
  • Unit symbol
  • Central figure
  • Main text

Back Side

Consider:

  • Motto
  • Date
  • Mission
  • Event information
  • Secondary emblem
  • Personalization
  • Numbering

Example

Front:

Central eagle + unit emblem + organization name

Back:

Mission statement + date + motto + commemorative text

The two sides should feel like part of the same design system.


7. Use the Coin Edge as a Design Element

Challenge coins can have different edge styles, including:

  • Rope edge
  • Reeded edge
  • Oblique edge
  • Diamond-cut edge
  • Plain edge
  • Textured edge

An edge can add another layer of visual identity.

For example:

Military challenge coin → Rope edge

Corporate commemorative coin → Reeded edge

Premium collectible → Custom edge

Edge selection should be made together with the overall artwork.


8. 2D vs. 3D Design

This is an important decision.

2D Design

Best for:

  • Logos
  • Text
  • Simple emblems
  • Flat artwork
  • Cost-sensitive projects

3D Design

Best for:

  • Eagles
  • Aircraft
  • Vehicles
  • Buildings
  • Animals
  • Portraits
  • Sculptures
  • Complex military emblems

Simple Rule

Flat artwork → 2D

Sculptural artwork → 3D

However, many successful products combine both.

For example:

3D eagle + 2D lettering + enamel background

This can create a strong visual effect without making the entire product excessively complicated.


9. How to Design a Custom Medal

Medals usually have a larger visual area than lapel pins.

That gives designers more freedom.

A strong medal design usually contains:

Central Symbol + Event Name + Year + Supporting Graphic

For example, a marathon medal could use:

  • Runner silhouette
  • Event logo
  • “2026”
  • City name
  • Marathon distance

Avoid Overloading the Medal

Adding too many:

  • Logos
  • Text blocks
  • Dates
  • Symbols
  • Colors

can make the medal look crowded.

A simple central image often creates a stronger final product.


10. Design for Sports Medals

Sports medals are often photographed and displayed.

Consider:

  • Large event name
  • Clear year
  • Sport-specific symbol
  • Strong 3D relief
  • Custom ribbon
  • Distinctive silhouette

For a soccer medal, for example:

Soccer ball + player silhouette + tournament name + year

is usually easier to recognize than a medal covered in small text.


11. Police Badge Design Guide

Police badge designs require special attention to identity and hierarchy.

Common elements include:

  • Shield shape
  • Eagle
  • Department name
  • Rank
  • Badge number
  • State or city
  • Department seal
  • Motto

The design should make the primary identifying element immediately visible.

For official products, the relevant department or authority should approve the artwork before production.


12. Military Badge Design Guide

Military badges and insignia often use symbolic elements such as:

  • Eagles
  • Stars
  • Shields
  • Flags
  • Weapons
  • Aircraft
  • Vehicles
  • Wings
  • Unit numbers
  • Mottos

A good military badge design should maintain clear separation between the main emblem and supporting information.

3D is Particularly Effective

A 3D eagle, aircraft, tank, or other symbol can create significantly more visual depth than a flat design.


13. Metal Badge Design

Metal badges are widely used for:

  • Companies
  • Hotels
  • Security teams
  • Schools
  • Clubs
  • Organizations
  • Events
  • Uniform identification

For corporate badges, simplicity is usually better.

A good corporate badge may only need:

Logo + Company Name

or

Logo + Department

There is no need to fill every available area.


14. Lapel Pin Design Guide

Lapel pins are small.

That means simplicity is critical.

A good 25–30 mm lapel pin might contain:

  • One logo
  • 1–3 colors
  • Simple border
  • Short text

Avoid:

  • Tiny paragraphs
  • Extremely thin lines
  • Too many colors
  • Highly detailed photographs

If the artwork contains too many details, consider increasing the pin size.


15. Keyring Design Guide

Keyrings provide more design flexibility than small lapel pins.

Possible shapes include:

  • Circle
  • Shield
  • Rectangle
  • Animal
  • Vehicle
  • Building
  • Logo
  • Custom silhouette

A keyring can also incorporate functional features.

For example:

  • Bottle opener
  • Ruler
  • Multi-tool
  • Screwdriver
  • NFC component

When designing a functional keyring, the artwork must be developed together with the mechanical structure.


16. Soft Enamel vs. Hard Enamel in Design

Your artwork should take the intended enamel finish into consideration.

Soft Enamel

Creates:

Raised metal + recessed color

Best when you want:

  • Strong color contrast
  • Textured appearance
  • Lower production cost
  • Bold graphic design

Hard Enamel

Creates:

Smooth metal + polished color

Best when you want:

  • Premium appearance
  • Smooth surface
  • Refined finish
  • Jewelry-like presentation

Do not simply convert a soft-enamel design into hard enamel without reviewing the production requirements.


17. Choose Colors Carefully

Most custom metal products use a limited number of enamel colors.

A strong design often uses:

2–5 main colors

rather than trying to use every available color.

For corporate products, Pantone references can help maintain brand consistency.

For example:

  • Primary brand color
  • Secondary brand color
  • White
  • Black
  • Metal finish

A limited color palette can actually make a product look more professional.


18. Think About Contrast

Contrast determines whether details are visible.

Good combinations include:

Dark metal + bright enamel

Antique gold + black

Silver + navy blue

Black nickel + white

However, the final appearance depends on plating and enamel color, so digital artwork should not be treated as an exact representation of the finished metal product.


19. Use Metal Lines Correctly

Metal lines separate different enamel areas.

If a design has extremely narrow metal lines, the manufacturer may have difficulty reproducing them consistently.

Instead of creating dozens of tiny separated areas, simplify the artwork.

A professional designer should ask:

Can this line still be clearly seen after the product is reduced to its actual size?

If the answer is no, make the line thicker or remove it.


20. Leave Enough Space Between Elements

Crowding is one of the most common problems in custom metal product design.

Allow enough space between:

  • Letters
  • Logos
  • Borders
  • Enamel areas
  • Relief elements
  • Decorative details

Good spacing improves both appearance and manufacturing reliability.


21. Select the Right Base Metal

Your design should also consider the base material.

Brass

Best for:

  • Premium challenge coins
  • Traditional military products
  • Heavy commemorative products
  • High-end badges

Zinc Alloy

Best for:

  • 3D challenge coins
  • Large medals
  • Complex badges
  • 3D keyrings
  • Irregular shapes

Iron

Best for:

  • Simple badges
  • Basic lapel pins
  • Cost-sensitive bulk products

The manufacturing method should be selected together with the design.


22. Plating and Finish

Common finishes include:

  • Gold
  • Silver
  • Copper
  • Black nickel
  • Antique gold
  • Antique silver
  • Antique copper
  • Dual plating

Polished Finish

Creates a clean and modern appearance.

Antique Finish

Creates contrast by leaving darker color in recessed areas.

For highly detailed 3D designs, antique finishing can be particularly effective because the darker recessed areas emphasize the relief.


23. Design for Manufacturing Cost

A more complicated design usually requires more:

  • Engineering
  • Tooling
  • Finishing
  • Enamel work
  • Quality inspection

This doesn’t mean you should always simplify your product.

Instead, identify which details actually add value.

Example

Removing 10 tiny decorative lines may reduce manufacturing difficulty without changing the overall appearance.

That is a good design improvement.

Removing the main emblem, however, may destroy the product’s identity.


24. File Formats for Professional Production

For the best results, provide vector artwork whenever possible.

Preferred formats may include:

  • AI
  • EPS
  • PDF
  • SVG

High-resolution PNG or JPG files can also be useful for reference, but vector artwork is generally easier for engineering and tooling.

Include:

  • Pantone colors
  • Dimensions
  • Front design
  • Back design
  • Edge design
  • Plating
  • Enamel type
  • Attachment
  • Packaging requirements

25. What Should a Production Drawing Include?

A professional specification sheet can include:

Product: Custom Challenge Coin

Diameter: 45 mm

Thickness: 3 mm

Material: Zinc Alloy

Sides: Double-sided

Relief: 3D

Enamel: Soft Enamel

Colors: Pantone references

Plating: Antique Gold

Edge: Rope Edge

Quantity: 1,000 pcs

Packaging: Individual velvet pouch

This reduces communication errors between the buyer, designer, engineer, and factory.


26. Quality Control During Manufacturing

A professional manufacturer should inspect the product at multiple stages.

Artwork Check

Confirm:

  • Dimensions
  • Text
  • Logo
  • Colors
  • Relief
  • Attachment

Tooling Check

Confirm:

  • Detail reproduction
  • Text clarity
  • Relief depth
  • Border structure

Production Check

Inspect:

  • Shape
  • Thickness
  • Surface
  • Enamel
  • Plating
  • Attachment

Final Inspection

Check the finished products against the approved sample or specification.

For large OEM orders, quality control is especially important because a small design error can be multiplied across thousands of pieces.


27. A Practical Design Formula

A simple formula for custom metal products is:

Strong Symbol + Clear Text + Controlled Color + Appropriate Relief + Correct Size = Better Product

For example:

Challenge Coin

Central emblem + organization name + date + motto

Medal

Sport symbol + event name + year + ribbon

Military Badge

Unit emblem + designation + symbolic elements

Lapel Pin

Logo + 1–3 colors

Keyring

Recognizable shape + logo + functional attachment


28. Study Case: Simplifying a Custom Lapel Pin

Imagine a company provides this design:

  • Company logo
  • Company name
  • Website
  • Phone number
  • Address
  • Slogan
  • Three decorative icons
  • Five colors

The proposed pin size is only 25 mm.

This is too much information.

Original Design

The artwork may look excellent on a computer screen but become unreadable after manufacturing.

Improved Design

Use:

Company Logo + Short Brand Name

Remove:

  • Website
  • Phone number
  • Address
  • Excessive decoration

The result is easier to manufacture and much easier to recognize.


29. Study Case: 3D Firefighter Challenge Coin

A firefighter organization wants a commemorative coin.

Requirements

  • 50 mm
  • Zinc alloy
  • Double-sided
  • 3D firefighter helmet
  • Fire axe
  • Department logo
  • 3 enamel colors
  • Antique silver

Recommended Structure

Front:

3D firefighter helmet + department name

Back:

Department logo + motto + year

Why This Works

The central 3D elements create depth while the enamel provides color contrast.

The design doesn’t try to make every element equally important.


30. Final Design Checklist

Before approving your custom product artwork, ask:

  • What will the product be used for?
  • Who will receive it?
  • Is it promotional, commemorative, collectible, or functional?

Size

  • What is the final size?
  • Is the text readable at actual size?

Artwork

  • Is the central symbol obvious?
  • Is the design too crowded?
  • Are the lines thick enough?

Color

  • How many colors are needed?
  • Are Pantone references available?
  • Will the color contrast with the metal?

Manufacturing

  • 2D or 3D?
  • Brass, zinc alloy, or iron?
