I collect Topps, Bowman and Fleer sets so collecting Mantle has just been a necessity. I think I have all of his Bowman and Topps issues except the 61 Dice, 66 Punch Out and 68 Disc. But being a variations collector as well, that meant 2 of the 52s.
I have no idea who is right about the future, but glad I bought when I did rather than wait for the prices to come down. Don't think I would have made it.
