Coin collectors, this 12-size assortment of cardboard coin holders is exactly what you need for organized, protected storage! The box includes different diameters from 17.5mm up to 40mm, covering most common coin sizes you'll encounter. Each holder is made from premium cardboard that's about 0.58mm thick - noticeably thicker than standard paper flips for better protection. When folded, they measure about 50x50mm, creating a compact, uniform storage system that looks professional and organized. The white color shows off your coins beautifully while keeping the focus on your collection. Here's the pro tip: choose a holder that's 0.5-1mm smaller than your coin's actual diameter for that perfect, secure fit. Each size comes with 50 holders, giving you plenty for organizing multiple coins of the same type or building sets. The simple fold-and-tuck design makes inserting and removing coins easy without damaging them. Whether you're storing common circulation coins or valuable collectibles, these cardboard flips provide that essential protection from fingerprints, scratches, and environmental damage. They're perfect for organizing by type, date, or mint mark, and they stack neatly in storage boxes or display pages. If you're serious about maintaining your collection's condition and value, these quality cardboard holders are an affordable, essential supply that every numismatist should have on hand.
