The COINFINITY 22.2mm Stacker is a purpose-built storage tube for 1/4 oz gold coins such as American Gold Eagles, Krugerrands, and Britannias. It offers secure, modular storage with embedded technology to help you digitally track and manage your collection.
Each stacker comes with a 25mm NFC tag embedded in the tube wall (not the lid), enabling quick tap-to-scan functionality using the COINFINITY App, available for both iOS and Android. With the app, you can view or update information about the coin inside—like mint, year, purchase value, and condition.
The lid and base include embedded 25mm x 4mm magnets (included), allowing you to securely stack this unit with other Coinfinity stackers, creating a stable, customizable storage system.
