Agree with Glyn. Card 80 Martin back cost me a lot. There are 3 versions, mine is the Left Grove front . It was expensive. The other two versions, Collins and Tinker fronts, are really expensive. Any of the versions will cost more than the rest of the entire set several times over.
There are a lot of Fleer retro card sets between 1959 and 1980, in addition to the "current player" 1963 set
This great blog offers info on those Fleer sets, including the 1960 set
