Will never have any combination of cards in my collection, which is almost all post war, than the 2 Mantle variations from the 1952 Topps set. There are some proof cards out there that could run that much, the 3 1951 unissued Topps Current All Stars of Roberts, Stankey and Konstanty, the 1960 proofs of Cimoli, Hadley and Throneberry, and the 68 3D prototype of F Robinson, but doubt I will ever get them
