The Three Old Proof Years
The Three Old Proof Years: 1873, 1877, and 1878:
Semi-Key Collecting, Part I
One way that I like to build my collection is by Semi-Key Collecting. Instead of getting all the common dates, I like to buy slightly rarer dates. I don't get extremely common dates, like the 1936 Buffalo nickel, or extremely rare dates, like the 1885 Liberty Nickel, but I get mid-mintage dates, like the 1894 Liberty Nickel.
