I saw what looked to be a tub / bin of assorted sports cards and started casually going through them - I'm a guy who can be entertained by rummaging through all this miscellaneous cardboard collecting dust, though I wasn't sure if I'd find anything of interest or if something was going to bite me back.
There were cards still individually priced from 20-25 years ago and I didn't want to ask about any junk cards with no prices] - I spent $2 on what looked to be 1978 TCMA The 1960's San Francisco Giants / California Angels team sets [in loose team set bags].
The Giants 'set' had a Masanori Murakami card on the back and figured picking up the 'set' for the individual Murakami card wasn't the worst buy for a dollar - I'm vaguely aware of TCMA sets but compared to mainstream, original Topps releases, the TCMA produced cards have less appeal to me as strictly collector issues.
After the fact, I looked up a checklist and discovered the Giants 'set' was missing the biggest name [Willie Mays #280] and also another notable [Orlando Cepeda #50] - not a big deal since Murakami was the card I really wanted.
The Angels set [complete unlike the Giants one] looked like it had the remains of a dead insect, but I took the cards out of the team set bag and cleaned the excess debris off with my shirt - the cards looked fine afterwards and after paying for the cards, threw the team set bag away.
