Why Fiber Lasers Are the Right Tool for Challenge Coins

Before getting into specific machines, it's worth understanding why fiber lasers dominate this application — and why other laser types fall short.

Challenge coins are typically made from brass, copper, zinc alloys, aluminum, or stainless steel. These are dense, reflective metals that require focused, high-energy laser interaction to engrave at any meaningful depth. Fiber lasers operate at a 1064nm wavelength that is highly efficient on metal surfaces — absorbed well by the material rather than reflected away, which is the key to clean, deep engraving.

CO2 lasers, despite their popularity for wood and acrylic, aren't effective on raw metal and won't give you the relief depth that challenge coins demand. Diode lasers can mark anodized aluminum or coated surfaces, but they lack the power density for genuine deep engraving on bare metal coins. UV lasers are precision tools for plastics and glass, not deep metal work.

MOPA fiber lasers specifically offer pulse width control that's particularly valuable for coins. Being able to vary the pulse duration opens up color annealing effects (black fills, gold tones on stainless) and gives you more nuanced control over the surface interaction. For collectors and premium work, MOPA machines are a meaningful step up.

"Challenge coin laser engraving, service/anniversary medals, or achievement awards can be a profitable laser engraving service. A fiber laser engraver delivers high energy density, produces clean and precise details for depth engraving, and works exceptionally well on brass, steel, and other metals." — ComMarker Laser Engravers

Essential Features for Challenge Coin Engraving

Laser Power and Type

For challenge coins, you need a fiber laser — specifically, 30W or higher for meaningful depth, and 50W or above for efficient deep relief engraving. MOPA fiber lasers offer additional control through pulse width variation, enabling color annealing effects and more precise surface interaction. The minimum viable setup for someone serious about coin work is a 30W fiber laser.

Work Area and Coin Fixturing

Standard challenge coins range from 38mm to 50mm in diameter. Any machine with a 100×100mm or larger work area can handle them. A 150×150mm field is more useful — it lets you engrave 4–6 coins simultaneously in a single run, which transforms production efficiency. Fixturing matters enormously: coins are small, round, and will shift if not properly secured. A custom jig or v-slot fixture that holds coins in consistent positions is essential for repeatable, centered engravings.

Software Compatibility

The two primary options are EZCAD (the traditional standard) and LightBurn (increasingly the preferred choice for its user-friendly interface and powerful design tools). For 3D depth map engraving — where a grayscale image creates relief depth by varying power across the design — LightBurn's control over density and layer settings is particularly well-suited to challenge coin work.

Engraving Depth Consistency

Deep coin engraving typically requires 20–40 passes for 1mm+ depth. The practical question isn't just how deep a machine can go, but how consistent it stays across dozens of passes without drift or surface variation. Running a cleaning pass between depth passes — at higher speed and lower power — removes residue and oxidation, keeping the surface clean for the next pass. This is standard professional practice.

Choosing the Right Machine for Your Situation

If You're Just Starting Out

The honest starting point is the Gweike G2 Max 50W or the LaserPecker 5, depending on whether you want maximum power for coin depth (G2 Max) or maximum versatility across materials (LaserPecker 5). Starting with a mid-range fiber laser and learning the craft — depth map design, multi-pass settings, coin fixturing — is more valuable than overspending on a machine before you know your workflow.

If You're Running a Small Business

The EM-Smart Nova 25W and ComMarker B6 MOPA both fit well here. The Nova is the right call if portability and compact footprint matter. The B6 is the right call if MOPA color effects and higher production speed are priorities.

If You're Building a Professional Production Operation

The Haotian 100W JPT MOPA Split Fiber Laser is the machine for this. For a business where engraving quality and machine reliability directly affect customer satisfaction and repeat orders, the investment is justified. The commercial market for challenge coins — military units, law enforcement, corporate clients — is large and well-established.

Frequently Asked Questions

What type of laser is best for engraving challenge coins?

A fiber laser is the correct choice. Challenge coins are made from metals — brass, copper, stainless steel, zinc alloys, and aluminum — and fiber lasers operate at the 1064nm wavelength most efficiently absorbed by metallic surfaces. CO2 lasers are not effective on raw metal. Diode lasers lack the power density for genuine deep engraving. For the best results, look for a fiber laser of 30W or higher. MOPA fiber lasers additionally offer pulse width control, enabling color annealing on stainless steel and more precise surface interaction for premium work.

How deep can a laser engrave a challenge coin?

Depth depends primarily on laser wattage and number of passes. A 50W fiber laser can achieve up to 5mm depth with sufficient passes. For most challenge coin projects, 0.5mm–1.5mm produces the relief effect and tactile quality that makes coins feel premium. Higher-powered machines (60W–100W) achieve the same or greater depth significantly faster, which matters for production volume. Multi-pass engraving with cleaning passes between sets is the standard professional technique for clean, uniform depth.

Do I need a MOPA fiber laser for challenge coins?

A standard fiber laser will absolutely produce quality challenge coins. MOPA adds pulse width control, which opens up color annealing effects (black fills, gold tones, gradient shading on stainless steel) and more nuanced surface control for very fine photographic-style relief. For standard deep relief engraving in the traditional challenge coin style, a quality standard fiber laser delivers excellent results. For coins that include color effects or collector-grade detail, MOPA is worth the investment.

What materials are challenge coins made from, and which engraves best?

Traditional challenge coins are made from brass, copper, zinc alloy, aluminum, and stainless steel. Brass is often considered the most forgiving — it responds well to fiber lasers, produces clean contrast, and achieves good depth. Aluminum engraves quickly with excellent contrast. Stainless steel requires more power or passes for equivalent depth but is the best material for color annealing effects with a MOPA laser. Black anodized aluminum is popular for lower-power setups because the laser removes the anodized coating to reveal high-contrast designs with minimal passes.

What software do I need for challenge coin laser engraving?

The two main options are EZCAD (bundled with most fiber laser machines and well-suited to galvo-based scanning) and LightBurn (increasingly popular for its more intuitive interface, now compatible with most fiber laser hardware). For challenge coin work — particularly 3D depth map engraving where grayscale images create relief effects — LightBurn's layer and density controls are particularly useful. You'll also need a design application (Adobe Illustrator, CorelDRAW, or Inkscape) for preparing artwork before it goes into the engraving software.

Is laser engraving challenge coins a profitable business?

Yes — challenge coins have strong economics. Blank stock typically costs $1–$5 per coin depending on material and size. A single custom challenge coin sells for $15–$75 at retail, with organisational bulk orders (military units, corporate events, law enforcement departments) typically ranging from $8–$25 per coin at volume. The customer base is wide and repeat-friendly — a military unit that orders coins for one group will order again for the next class or deployment.
