Mint cellos from the sixties are virtually impossible to locate and this 1965 Topps 5th series cello pack graded PSA 9 fits the bill, with none graded higher.  Highlighted by Roberto Clemente, the 1967 Topps 5th series also features Pete Rose and Willie Mays/Wille McCovey “Fence Busters.” As summer turned into the autumn of ’67, and the Red Sox and Cardinals were about to do battle in the fall classic, these packs were on the shelf.
