PSA MINT 9. The 1963 Fleer baseball card set was intended to have multiple series, and was likely to be 500-600 cards in length. However, the ensuing court fight between Topps and Fleer over "exclusive rights" necessitated Fleer limiting their issue to only one series. The most popular card to this 66-card set is Roberto Clemente, #56 on your unnumbered checklist. This example is dead-on perfect, with razor sharp corners, white borders and clean surfaces front and back. A very nice, recently graded example. PSA graded MINT 9.
