Coin collectors, this album is a game-changer for organizing your collection! With 312 pockets total, you've got plenty of space for all your coins. Here's the breakdown: 10 pages with 24 pockets each (that's 240 pockets measuring 30x30mm/1.18x1.18 inches) plus 6 pages with 12 larger pockets each (72 pockets at 46x46mm/1.8x1.8 inches). That means it can handle coins from 20mm all the way up to 46mm - so everything from pennies to silver dollars, half dollars, challenge coins, tokens, medallions, you name it. The pockets have little flaps to keep your coins from sliding out, and the transparent pages let you see both sides without removing anything. The exterior is made of sturdy PU material that feels quality, and the whole book measures about 8.25x6.1x1.7 inches - compact enough to carry with you or store easily. Perfect for showing off your collection to friends or just keeping everything organized and protected from dust. Makes a great gift for any coin collector in your life too!
