When it comes to storing and protecting your precious coins, the right airtight capsule is key. For those in possession of Australian 1oz silver coins, there are a few options available. The diameter of these coins is 40.6mm, and it is important to get the right fit to ensure the coin stays in place and does not rattle. Air-Tite capsules are a popular choice, with their H40 model designed for a direct fit with 1oz Silver Eagles, and also accommodating 1oz Silver Australian Coins, including the Kangaroo, Koala, Kookaburra, and Crocodile. The Air-Tite H39 model, on the other hand, is designed for coins with a 39mm diameter and 3.17mm thickness. While some sources suggest that exact sizing is important, others advise that a 40mm capsule will do the job for the Australian 1oz silver coins.
