Got a coin collection that needs some TLC? These clear plastic capsules are the perfect way to protect and display your coins. This specific pack gives you 100 capsules, all sized for coins that are about 18mm in diameter (that's roughly the size of a US nickel or a UK one pound coin – but definitely measure your coins first!). They're made from sturdy, transparent plastic so you can see both sides of your coin clearly without ever having to take it out and risk fingerprints or damage. They have a clever crescent-shaped opening on the side, which makes it really easy to snap your coin in and out without scratching it. They provide a safe, dust-free, and air-tight-ish environment to keep your coins in mint condition. Perfect for collectors of all levels, whether you're organizing a new find or upgrading the storage for your whole collection. They also make a great gift for the coin enthusiast in your life. Simple, effective, and super affordable protection.
