When ordering custom challenge coins, medals, or lapel pins, one of the most common questions buyers ask is: What's the difference between 2D and 3D designs? The answer affects not only the final look and feel of your product but also the cost and production timeline.
In simple terms, 2D designs have two levels of metal—raised and recessed—creating a clean, graphic look. 3D designs have multiple levels with sculpted, rounded surfaces that create a realistic, lifelike appearance.
What Is 2D Design?
A 2D design (also called flat or two-level design) is the standard for most custom coins, medals, and pins. The design has two distinct levels: raised metal (the design elements that stick up) and recessed metal (the background areas). The raised metal outlines the graphics, while the recessed areas are typically filled with enamel color or left blank for contrast.
Key Characteristics:
Two levels of metal: raised and recessed
Clean, sharp lines and graphic appearance
Ideal for logos, text, and flat illustrations
Easy to add enamel colors in recessed areas
Lower cost and faster production
Works well on smaller coin sizes
Common Applications for 2D Design:
Corporate logos and brand identity pins
School and university mascot pins
Sports team medals with event text and dates
Employee recognition and service awards
Promotional giveaways and bulk orders
When to choose 2D:
Your design includes detailed text or a complex logo
You need multiple enamel colors in the design
You have a tighter budget
You need faster delivery
Your coin size is smaller (under 1.75 inches / 44mm)
What Is 3D Design?
A 3D design goes beyond the two levels of a 2D coin. It uses a sculpted, multi-level surface with rounded edges and smooth gradations between raised and recessed areas. Instead of flat levels, 3D designs have unlimited levels of depth, creating a realistic, lifelike appearance.
Key Characteristics:
Multiple levels with rounded, sculpted surfaces
Realistic, lifelike appearance with depth and shadows
Ideal for faces, statues, buildings, vehicles, animals, and natural textures
Best left as all-metal design (no enamel fill on 3D areas)
Higher cost and longer production time
Requires larger coin size (over 1.75 inches / 44mm) for best detail
Why 3D Designs Are Popular for Collectors:
3D designs create a museum-quality look that collectors value. The sculpted details catch light differently from different angles, giving the coin a dynamic, ever-changing appearance. This makes 3D coins more desirable as keepsakes and collectibles—they feel like miniature sculptures rather than flat tokens.
When to choose 3D:
Your design includes realistic elements like faces, statues, or buildings
You want a premium, high-end look and feel
You are creating collector items or commemorative pieces
Your coin size is larger (over 1.75 inches / 44mm)
You can work with antique plating (which highlights 3D details)

Manufacturing Processes
Understanding the manufacturing process helps explain why 3D designs cost more and take longer.
2D Process: Die-Striking
Mold Making: A CNC machine engraves the 2D design into tool steel
Production: A hydraulic press stamps the design into a metal blank under hundreds of tons of pressure
Finishing: Excess metal is trimmed, plating is applied, and enamel colors are added to recessed areas (if applicable)
Common metals for 2D die-striking: Zinc alloy, brass, and iron.
3D Process: Die-Casting
Mold Making: A CNC machine carves the complex 3D contours into steel (takes much longer than 2D)
Production: Molten zinc alloy is injected into the 3D mold under high pressure
Finishing: Excess material is trimmed, and antique plating is often applied to highlight the 3D details. 3D areas are left all-metal (no enamel fill on sculpted surfaces).
Why zinc alloy for 3D? Zinc alloy has a lower melting point and excellent flowability, allowing it to fill every tiny crevice and curve of the intricate 3D mold. This captures sculptural detail perfectly.
Mold Storage and Reusability:
After your order is completed, we store your mold for up to 3 years at no additional charge. This allows you to reorder the same design without paying the mold fee again. If you do not place a reorder within 3 years, the mold will be discarded to free up storage space. Should you need the same design after that period, a new mold would need to be created. We recommend keeping your digital artwork files safe so we can recreate the mold if needed.

Our team has over 15 years of experience working with zinc alloy, brass, and iron. Whether you need 100 pieces or 10,000, we can accommodate your order with consistent quality and fast turnaround.
Cost Factors to Consider
Several factors affect the final cost of your custom coins or pins. For 2D designs, the main cost drivers are size, material, enamel colors, and quantity. For 3D designs, the mold is the biggest upfront investment—3D molds cost significantly more than 2D molds due to the complexity of carving sculpted contours. However, the mold is a one-time fee that can be reused for future reorders. Larger quantities also lower the per-unit cost. Contact our team with your artwork for an accurate quote.
Color Considerations
One of the most important practical differences: 2D designs are much easier to color, while 3D designs are typically left as all-metal pieces.
2D Coins: Easy to Color
The recessed areas provide perfect reservoirs for soft or hard enamel
Multiple colors can be added to different recessed levels
Great for flags, logos, and designs with brand colors
Colors are protected by raised metal borders
We offer Pantone color matching for all 2D enamel-filled designs—simply provide your color code, and we will match it precisely. Our in-house color lab ensures consistency across every batch.
3D Coins: Best Left All-Metal
The sculpted 3D surface cannot be enamel-filled without losing detail
If colors are needed, they can be added to flat background areas around the 3D elements
Antique plating is the most popular finish for 3D coins—it highlights depth and creates beautiful light/dark contrast
Pro Tip: If your design absolutely needs multiple colors and 3D realism, consider a hybrid approach: use 3D for the main sculpted element (like a statue or logo) and 2D with enamel colors for the background or border elements.
Size Matters: 2D vs 3D on Different Coin Sizes
Under 1.5 inches (25–38mm): 2D designs work excellently for logos, text, and simple designs. 3D designs are not recommended—the fine detail will be lost at this size.
1.5 – 1.75 inches (38–44mm): 2D designs deliver great detail clarity. 3D designs are possible but offer limited detail at this size.
1.75 – 2.0 inches (44–50mm): 2D designs maintain excellent detail. 3D designs start to show their full potential at this size.
2.0 – 2.5 inches (50–64mm): 2D designs are excellent for complex artwork. This is the best size for 3D designs—all detail is clearly visible.
On smaller coins, 2D designs allow for more distinct details. With 3D coins, smaller details can become lost or hard to distinguish. For 3D designs, we recommend ordering 1.75 inches (44mm) or larger.

Client: A regional marathon organizing committee
Design: Front: 2D event name, date, and distance markers with enamel colors. Back: 3D sculpted runner and trophy.
Why they chose hybrid: The front needed clear, readable text for the event details (2D was the best choice). The back needed a realistic runner figure to capture the spirit of the race (3D made it come alive).
Result: A stunning combination of clear text and sculpted detail. 500 medals delivered in 15 days with both 2D and 3D elements on one coin. Produced by AQ PINS & GIFTS.
Frequently Asked Questions
Q1: Can my 2D logo be made into a 3D coin?
A: Yes. Our 3D artists can take your flat 2D logo and skillfully interpret it into a 3D model, adding depth, beveling, and texture to bring it to life in a sculptural form.
Q2: Is a 3D coin always "better" than a 2D coin?
A: Not at all. They are different tools for different jobs. For a clean, bold corporate logo, a 2D coin is often superior because it's more readable and graphically precise. 3D is only "better" when the goal is realism and sculptural depth.
Q3: What is the minimum order quantity for 2D vs 3D?
A: There is no minimum order for either design type. Whether you need just 1 sample piece or a bulk order of 10,000, we can accommodate your needs.
Q4: Can medals be made in both 2D and 3D designs?
A: Yes. Medals are one of our most common 2D/3D hybrid products. Many sports events use 2D on the front for clear event text and 3D on the back for sculpted trophies or athlete figures. This combination gives you the best of both—readable details and a premium, collector-grade look.
