Littleton albums provide archival-quality acid-free and PVC-free long-term storage for your collection. Each album gives you a brief history about the series along with mintage figures. Littleton albums feature sturdy 3-ring binder construction so album pages lie flat and can be easily removed. Brass eyelets reinforce the pages and thumb-holds make slide removal convenient. Crystal-clear slides show both obverse and reverse. Album fits in a 2-inch slipcase (sold separately).
