Like RawGoo, I collect too much!
Besides Wackys and almost all Wacky knockoffs I collect sports cards. I just finished my 1972 Football, and I've got about 50 cards left to finish the 69, 70, and 71 sets. I was working on 1972 Baseball, but it's just too hard to get the 5th and 6th series cards at a decent price. I have the 1973-77 sets in both of these along with Basketball too. I think once I finish these last three sets, I'll quit.
Weirder things are
Baseball and Football Slurpee Cups from 1972 and 1973
I also really like certain sports sets and oddball sets that were separate from the basic Topps sets, but during the timeframe when Topps was still the main draw in sport cards. Examples:
-Hostess Baseball 1975-1979 - very nostalgic about these but chances are slim to none I’ll ever complete a single year’s set, let alone all five.
-Kellogg’s Baseball 3-D / hologram cards - love these too but hard to keep the surface coating from cracking
-Fleer World Series cards (cartoon summaries of each year’s Fall Classic, drawn by Laughlin)
-Sugar Daddy Pro Faces (all 4 sports) - small narrow cards inserted in Sugar Daddy pops. Only have a few of these from childhood Halloween trick or treating.
-Fleer Team Action / Teams in Action football 1976-1988 - great action scenes with no licensing issues. Helmet logos didn’t have to be airbrushed out like on Topps single player cards. First discovered these as Halloween booty also. Also had little team logo and helmet sticker subsets for each year.
-7-11 Slurpee baseball discs (hologram)
-Cracker Jack mini baseball
-1982-83 Post cereal mini hockey cards - these were issued in Canada only I believe, each box prize was a cello-wrapped team set, and they were intended to be used as part of a card game of some type, once you got all the teams. But the fronts still had basic player/action photos. Only recently learned about them on eBay.
