Coinfinity Bin – 1×2 Assay Organizer (70×148 mm)

Store and display your assay cards, graded slabs, and collectible bars with precision.
The Coinfinity 1×2 Assay Bin is a modular storage tray designed for mint-sealed gold and silver bars, assay packaging, and encapsulated coins. It fits perfectly within the Coinfinity modular grid system, keeping your collection aligned, organized, and professional.

Built from the ground up for collectors, every Coinfinity Bin matches the height and footprint of standard Coinfinity Stackers — so you can mix and match bins and tubes in the same base layout. Each bin prints cleanly without supports, and its smooth PETG surface keeps precious metals safe from reactivity or scratches.

Whether you’re storing 1 oz silver bars in assay cards or premium graded coins in slabs, this bin brings order and consistency to your setup while maintaining the signature Coinfinity look.
