Modular Challenge Coin Display Rack

After decades of collecting challenge coins, I realized that traditional display racks just aren’t scalable. To solve this, I designed a modular, expandable display system that grows alongside your collection.

This low-profile rack lies flat, making it a perfect fit for desks or cabinets. Each 8" x 8" panel features six rows of 1/4" grooves designed to accommodate coins of various sizes. A single panel can hold approximately 24 coins.

Design Features

• Modular Connectivity: Panels connect front-to-back using a secure tongue-and-groove system. The fit is snug enough to hold on its own but can be made permanent with some super glue.
• Side-to-Side Stability: For lateral expansion (left, middle, right), the rack uses snap-in connecting pieces to keep everything aligned on your surface.
• Versatility: With 7 different panel types, you can customize the footprint to fit your specific space.

Configuration Guide

Choose your panels based on your desired layout:

Configuration	Panels Required
1x1 (Standalone)	Panel 7 (Finished edges; not expandable)
1x2	Panels 1 & 3
1x3	Panels 1, 2, & 3
1x4	Panels 1, 2, 2, & 3
2x2	Panels 1, 3, 4, & 6
2x3	Panels 1, 2, 3, 4, 5, & 6
2x4	Panels 1, 2, 2, 3, 4, 5, 5, & 6

Note: To make any "1x" or "2x" configuration wider, simply print additional Panel 2s (for the front) or Panel 5s (for the back).
