Newly discovered partial set of 1952 Bowman cards (112/252), all graded by PSA. A breakdown of the total number of cards, per grade, is shown here including some of the better names: PSA 7 (16): Irvin, Dressen, Sisler. PSA 6 (30): Furillo, Roberts. PSA 5 (45): Mantle, Rizzuto, Kiner, Reese. PSA 4 (19): Mays, Musial, Campanella, Berra. PSA 3 (2). These cards are seeing daylight for the first time in 15 years and there are cases are from the early days of PSA grading, so there may be possibilities for upgrades.
