This album includes spaces for the specially made Proof Presidential Dollar coins from the San Francisco Mint. 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).
