Calling all coin collectors! This 100-piece set has everything you need to protect and organize your valuable collection. You get 30mm clear plastic capsules that snap together securely to keep coins dust-free and safe from oxidation. The capsules have this clever crescent-shaped opening on the side that makes them super easy to open and close - no more struggling or breaking nails! But here's the really smart part: you also get 100 foam gaskets in five different sizes (17mm, 20mm, 25mm, 27mm, and 30mm) that you can trim to fit any coin perfectly. These little rings stop your coins from sliding around and getting scratched inside the capsules. The plastic is nice and thick - not that flimsy stuff that cracks easily - and crystal clear so you can actually see both sides of your coins without removing them. The whole set comes in a handy storage box that keeps everything organized and easy to find. Whether you're protecting rare coins, commemorative issues, or building a collection for the future, these capsules give museum-quality protection at a fraction of the price. They're perfect for silver dollars, half dollars, foreign coins, or any collectible coins up to 30mm in diameter. Seriously, if you're tired of coins getting damaged or just want a professional way to display your collection, this set is exactly what you need.
