The COINFINITY 17.5mm Stacker is a precision-designed, modular storage tube built for collectors of 1/10 oz gold coins such as American Gold Eagles, Britannias, Philharmonics, and other small-format bullion. Each unit includes a 25mm NFC tag embedded directly in the tube wall (not the lid), allowing you to scan and identify your coin using the COINFINITY App, available on both iOS and Android. Simply tap your phone to the tube to view or update the digital record of the coin inside—perfect for tracking origin, value, purchase history, and more. The lid and base also feature embedded 25mm x 4mm ceramic magnets (included), enabling secure, vertical stacking with other COINFINITY stackers. Whether you're organizing your vault or building a display, these tubes keep your coins smartly stored and ready to identify with a tap. 17.5mm Stacker Capacity: Typically holds ~50–60 coins depending on thickness Compatible with: Coin Name Diameter Thickness Mint 1/10 oz Gold Maple Leaf 16.00 mm 1.22 mm Royal Canadian Mint 1/10 oz Gold Britannia 16.50 mm 1.19 mm The Royal Mint 1/10 oz Gold Kangaroo 16.10 mm 1.30 mm Perth Mint 1/10 oz Silver Maple Leaf 16.50 mm 1.35 mm Royal Canadian Mint 1/10 oz Silver Britannia 16.50 mm 1.30 mm The Royal Mint 1/10 oz Silver Kangaroo 16.50 mm 1.25 mm Perth Mint 1/10 oz Platinum Maple Leaf 16.00 mm 1.14 mm Royal Canadian Mint 1/10 oz Platinum American Eagle 16.50 mm 1.19 mm United States Mint 1/10 oz Platinum Britannia 16.50 mm 1.19 mm The Royal Mint 1/10 oz Platinum Philharmonic 16.00 mm 1.20 mm Austrian Mint Features: ✅Internal Diameter: 17.5mm ✅Ideal for 1/10 oz gold coins (e.g., Gold Eagles, Britannia's, Philharmonics) ✅25mm NFC tag included and pre-installed in the tube wall ✅Compatible with the COINFINITY App (iOS & Android) ✅Embedded 25mm x 4mm magnets in lid and base for secure stacking ✅Size embossed on the lid for easy visual reference ✅Fully modular with all other COINFINITY stackers ✅Designed and manufactured in the USA Material & Finish: ✅Made from high-quality PETG, depending on selected color ✅Rigid, heat-resistant, and safe for use with metal or capsule-stored coins ✅Smooth matte finish with light texture for grip ✅Printed with precision for tight tolerances and long-term durability ✅2x Units Included - 2 Pack
