@JordanRC-com ... "Another 1993 parallel card that's difficult to track down is Alomar's 1993 Pinnacle Cooperstown Dufex single (#29). This is a limited edition foil version of Alomar's regular 1993 Pinnacle Cooperstown card. In a 2007 interview, B.A. Murry, owner of Bam! Cards in Carbondale, Ill., noted that the 1993 Pinnacle Cooperstown Dufex set was "a non-commercial set" offered as a prize to Sports Collectibles Association International (SCAI ) members that attended every meeting leading up to the November 1993 SCAI conference.
At that time, Murry owned a copy of the letter that accompanied these sets. The letter revealed that 1,000 sets were produced and that some were mailed out in February 1994. Nowhere near 1,000 SCAI members, however, attended all of the meetings, so there's some debate as to what happened to the leftover sets. Jim Kramer, owner of Southpaw Cards in Roseville, Minn., told me in a 2007 interview that he believed that only about 150 to 200 of these sets were still in existence.
