The COINFINITY 27.4mm Stacker is a precision-designed storage tube built for coins with a 27.4mm diameter. It delivers secure, modular storage while integrating embedded NFC technology to help you digitally track and manage your collection with ease.
Each stacker includes a 25mm NFC tag embedded directly into the tube wall (not the lid), enabling seamless tap-to-scan functionality using the COINFINITY App, available on both iOS and Android. With a simple tap, you can instantly access or update details about the coin inside — including mint, year, purchase price, metal type, and condition.
The lid and base feature embedded 25mm x 4mm ceramic magnets (included), allowing you to securely stack this unit with other Coinfinity stackers. Build a clean, stable, and fully modular storage system tailored to your collection.
