Traded away 3 Jerry Rice rc’s for practically nothing (baseball of all things) when I just got back into the hobby of collecting in ‘90.
Traded away Gretzky SOTT, Lindros BAP Stick, and Gretzky/Messier Ice Stanley Cup Foundations cards in a single deal for a couple of cards incl a 96-97 Zenith box, about $150 in value. Got a Gretz/Mess SCF back in a great deal, but shoulda made a better inital trade. It was ‘98.
Went to a card show and sold/traded SPGU Crosby auto #’s, Lemieux SPGU patch, ORR SPGU auto /50, RNH/Landeskog SPGU xtra auto/25, and a Landeskog or Duchene UD RC (can’t remember, too many yrs ago). Not really complaining but ended up doing better that I thought I would. Got some cards that I wanted and $150 in cash. Only thing, shoulda held onto the Orr auto. That is gold now.
And 2 coulda’s...LSC got 2 boxes of 06-07 Artifacts, I grabbed one, decent box...but the other box had a Calgary Tundra Tandems 1/1 tag. Meh! LCS had 05-06 ICE, grabbed a stack (1/2 box, all that I could afford), pulled a Koivu patch! Rumor had it, 9 out of 10, if they had a patch, they had /99 RC. Not sure if the /99 was in the box. (Probably was Brule anyhow.)
By practice, I try not to buy retail as I see that as a money grab by the companies but accidentally bought some retail artifacts buying a variety of loose packs from a LCS in Binghamton a few years ago. If I had known, I woulda not bought them, but the Hockey Gods were watching me that day and I pulled a Joe Thornton Autofacts!!! It was a 09-10 retail pack!!!
