This album includes spaces for all regular issues from the P, D and S Mints from 1916 to 1947, including 1917 obverse and reverse mint mark varieties. 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).
