D. C. MarkelI too have heard that Reggie Jackson tried to corner the market on his '69 Topps rookie card. In fact a dealer friend of mine made a "find" of several '69 vending boxes from that same series in the late '80s and sold all 23 rookie cards he pulled from that find and made the deal with Reggie in person.
I also know a person who tried to corner the market on vintage PSA 10 cards (basically cards from the early '50s to the mid-70's). Needless to say, that venture failed.
