This album includes spaces for all regular P, D and S Mint issues from 1913-1938, including 1913 Varieties 1 and 2 from all 3 Mints, plus 11 extra spaces. 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 1.5-inch slipcase (sold separately).
