I was lucky enough to stumble across two of these old coin books, both from 1963! One is a partially filled collectors book and the other is a price guide. Unfortunately the silver coins did not tone well. Look at some of these prices!
I have a complete set of Mercs in a 1963 Whitman. I should be stabbed for having a 16-D and a 42/41 in an old book that I know will cause toning. But I just love the old book.
