🚀 Most Stacks start small and grow quickly!

When you start stacking coins, at first you don’t need much organization. Just throw them in a box and call it a day. But as your collection grows, you’ll find that you need/want more organization. Coinfinity is a modular system that allows you to store and track your entire collection in a way that is both secure and easy to use.

There aren’t many “Universal” storage solutions for coins and bullion. Add in Slabbed coins and Assay cards and it gets even more complex!

Coinfinity grows with your stack. You can 3D print the stackers, bins and bases you need as you go. We sell 4 packs of stackers in our store if you would rather just buy them ready made. Coinfinity.US

Coinfinity, brings ORDER to CHAOS! Finally, a system designed to help you store and track your entire collection! Coinfinity isn’t just Stacker Tubes, it’s Bins for Assays, Bars, Slabbed coins and a Mobile App to track your entire collection! Each of the “badges” contains a unique NFC tag that can be used to track the contents of each bin.
