The COINFINITY 41.0mm Stacker is engineered to hold larger-format coins such as American Silver Eagles, silver Krugerrands, and other rounds or capsule-stored coins up to 41.0mm in diameter. It’s perfect for collectors looking to combine modern organization with smart tracking technology.
Each stacker includes a 25mm NFC tag embedded in the wall of the tube (not the lid), enabling tap-to-scan functionality with the COINFINITY App, available for both iOS and Android. Instantly access your coin's stored data including year, mint, value, condition, and notes—right from your phone.
Stackers are magnetically aligned and securely held using 25mm x 4mm ceramic magnets (included) in both the lid and base, making them fully compatible with other COINFINITY modules.
