As a kid I kept a
Jefferson nickel collection in a "Treasury of Coins" album which consisted of several heavy cards. The labeled coin holes were backed with clear plastic. The cards fit into a sturdy cardboard sleeve with photos and printed information about the series. I thought it was a nice-looking album, more professional-looking than the basic Whitman folder. After years of storage on a bookshelf I discovered the backs of most of the coins had the same green corrosion you show on that Buffalo. The metal was deeply pitted in places and the coins were ruined. No great financial loss since all the coins were circulated pieces pulled from circulation. It was however very disappointing to learn that the "nice" album I selected to display and preserve my collection turned out to be not such a good choice.
