Calling all coin collectors! These 2x2 coin flips are perfect for protecting your valuable nickels and other small coins. Each flip is made from archival-grade white cardstock with a crystal-clear polyester window that lets you see both sides of your coin without ever having to remove it. They're specifically sized for US nickels (21.2mm) but work great for other small coins too. Using them is super simple - just slide your coin in, fold over the top, and seal it with a staple or tape. The white background gives you plenty of space to write important info like dates, grades, or any special notes about your coins. The best part? These flips fit perfectly into standard 2x2 storage boxes and 20-pocket binder pages (like the BCW LaserWeld ones), so organizing your collection is a breeze. They're an affordable way to protect your coins from fingerprints, dust, and damage while keeping everything neatly cataloged. Whether you're a serious collector with valuable coins or just starting out with pocket change finds, these flips offer professional-level protection without the high cost. Dealers, hobbyists, and shop owners love them because they're durable, easy to use, and make coins look great for display or trading. Stock up on these - you'll be surprised how quickly you go through them once you start organizing your collection!
