I only have 3 Topps test issues - the 1968 Plak and Disc, and the 1969 Super of Harmon Killebrew. I used to own most of the Plaks, several 1955 stamps, a 1961 Dice Game of Earl Battey, some 1970 Cloth Stickers and Candy Lids, some Punchouts and full sets of some of the easier issues like the 1974 Puzzles and 1967 Boston and Pittsburgh stickers. I never dreamed when I sold everything off around 20 years ago that it would be so hard to find them again; as late as 1991 the scarcest things I had barely fetched $100. Oh well. I'm still looking for a 1968 single panel Killebrew Action All-Star Sticker, and a 1967 Giant Stand-Up...
