Coin collectors, these FRIMOONY capsules are exactly what you need to protect and organize your collection! The 46mm size is perfect for most standard coins - think silver eagles, US quarters and dollars, pennies, challenge coins, and more. Each capsule has an inside diameter of 46mm and height of 3mm, with the outside measuring 51x6mm. What's really smart are the included foam gaskets - you get 8 different sizes (17mm to 46mm) that you can trim to fit your specific coins perfectly, preventing them from moving around inside the capsule. The crescent opening design makes these super easy to open and close without struggling or risking damage to your coins. The PS material is crystal clear, so you can admire both sides of your coins without removing them from protection. The package includes 40 capsules, 40 foam gaskets, and a handy plastic storage box to keep everything organized. The quality is immediately noticeable - these aren't flimsy plastic that will crack easily. They provide excellent protection from fingerprints, dust, moisture, and other environmental factors that can damage coins over time. Whether you're a serious numismatist or just starting your collection, proper storage is crucial for maintaining coin condition and value. These capsules make it easy to handle and display your coins while keeping them in pristine condition. The storage box is a nice bonus for keeping your encapsulated coins organized and protected from scratches. For the price, you're getting professional-grade coin protection that will keep your collection safe for years to come!
