🔒 Coinfinity Modular System – Stackers, Bins & Accessories
The Coinfinity System is a modular, magnetically stackable storage and display ecosystem for coins, rounds, slabs, and assay cards.
Each unit connects seamlessly using 25 mm magnets and optional NFC tags for digital tracking and organization.
Designed for collectors of Gold, Silver, Platinum, and Palladium — made to protect and showcase your stack.
🪙 Coinfinity Stacker – 41 mm
The 41 mm Coinfinity Stacker is one of the most popular sizes in the Coinfinity Modular System. It’s designed for standard 1 oz silver coins, including American Silver Eagles, Maple Leafs, Britannias, and Krugerrands.
Each stacker provides a snug fit that keeps coins secure, aligned, and protected. The twist-lock lid prevents movement and dust, while the built-in magnetic base allows you to stack, display, and organize your coins with precision.
Optional NFC integration lets you digitally identify and track your collection using your phone — just tap the lid to reveal what’s inside.
