From picking a size to approving the artwork proof, here's how to plan a coin or pin project that arrives on time and looks the way you pictured it.

A well-made challenge coin or lapel pin does something a printed thank-you card can't. People carry it, trade it, and pin it to a jacket they wear for years. Companies use them to mark anniversaries, clubs use them as membership tokens, and event organizers hand them out as keepsakes.
Most people order one only every few years, so the process feels unfamiliar each time. This guide walks through the decisions in order so you can brief a manufacturer with confidence.
Step 1: Decide what the item is for
- Recognition or awards call for weight and presence. A thicker coin, antique plating and a detailed back design suit this.
- Membership or team identity works best as a pin people wear every day, so keep it small, light and clear.
- Event giveaways need to be produced reliably on a fixed date. Simple, bold designs with fewer colors reduce risk.
Unsure between a coin and a pin? Coins live in pockets, on desks and in display cases, while pins go on lapels, lanyards, caps and bags.
Step 2: Choose the size
Challenge coins are commonly 38–50 mm in diameter and about 3–4 mm thick. Smaller coins feel like tokens, while 45 mm and up gives you room for detail on both sides. Shaped coins, such as shields, dog tags or logo outlines, are possible too.
Lapel pins usually fall between 20 and 30 mm on the longest side. Below about 18 mm, text becomes hard to read. Above about 35 mm, a pin starts to feel more like a badge.
A quick trick is to print your design at a few sizes, cut them out, and hold them against a jacket or in your palm.
Step 3: Pick a finish that matches the design
These are the finishes you'll come across most:
- Soft enamel: Color sits in the recesses below raised metal lines, giving a textured, tactile surface. It's versatile, vibrant and popular for both coins and pins.
- Hard enamel (cloisonné-style): Enamel is filled level with the metal lines and polished flat for a smooth, jewelry-like look. It's especially durable for pins worn every day.
- Baked lacquer: A painted color fill that suits bright, flat graphics, and it's often paired with a protective coating.
- Epoxy dome: A clear resin layer over the surface that protects the colors and adds a glossy, slightly raised look.
- Rubber (soft PVC) fill: A flexible, slightly matte color fill. It gives an unusual soft-touch feel on coins and a modern look on some pins.
- Antique plating: Bronze, silver, gold or copper plating with darkened recesses that brings out sculpted 3D detail. This is the classic choice for military-style and commemorative coins.
You can combine them. A coin might have an antique bronze 3D relief on one side and soft enamel color on the other. A pin might use polished gold lines with hard enamel fill.

Step 4: Prepare artwork and review the proof
A clear sketch or logo is often enough for the factory to redraw the design, but the better your brief, the fewer revision rounds you'll need. Include:
- Your logo in vector format, if you have one
- Pantone color references
- Text exactly as it should appear, double-checked for spelling and dates
- Notes on what should be raised, recessed, 3D sculpted or colored
The manufacturer will return a digital proof showing the dimensions, color callouts, plating and line structure. Have someone outside the project read it too, and check names, years and small text with extra care. Once the mold is cut, changes mean starting over.
Also confirm the details that are easy to overlook: the edge style for coins (plain, rope or diamond-cut), the back attachment for pins (butterfly clutch, rubber clutch, magnet or locking pin), and packaging such as poly bags, velvet pouches, coin capsules or backing cards.
Step 5: Build your timeline backwards
Most delays come from starting too late, so work back from the day you need the items in hand:
- Shipping and customs: Allow time for international transit and clearance.
- Production: Plating, coloring, polishing and packing usually take a few weeks after sample approval.
- Sample approval: Request a physical sample if the project is high-profile or uses unusual finishes.
- Mold making: This starts once the proof is signed off.
- Proof revisions: Plan for at least one or two rounds.
Ask for a realistic schedule at the quoting stage and add a buffer for public holidays. For a fixed event date, starting two to three months ahead is comfortable.
Step 6: Think about quantity sensibly
Molds are made once per design and can usually be reused for reorders, so a second batch is quicker than the first. Many manufacturers accept small first orders, sometimes 50–100 pieces per design, which suits clubs and one-off events. If you're planning several versions, such as different years or ranks, ask whether a shared design with changeable details could reduce the number of new molds.
Bringing it together
A good coin or pin project comes down to a clear purpose, a sensible size, finishes that suit the artwork, a carefully checked proof and a timeline with room to breathe.
