41mm Round Coin Capsules are an essential accessory for collectors of both silver and gold coins. Made from crystal-clear acrylic, they provide a snug, protective display for coins up to 41 mm diameter and ~3.0 mm thickness. These capsules also work as a versatile, multi-purpose option for coins that are slightly smaller, with a loose but usable fit (spacers or foam rings recommended).
