A 50-home run season was quite an accomplishment back in the day. It's a little more common nowadays. This creamy-white ONL/White ball has been signed by six members of the 50 Home Run Club: Mickey Mantle (sweet spot), Willie Mays, Johnny Mize, Cecil Fielder, Ralph Kiner and George Foster. The crystal-clear blue pen applications grade a solid (“9 to 10”). Full LOA from PSA/DNA. Opening Bid $200.
