*UPDATE*
While sorting through all the junk my "spidey senses" told me to research some of the stuff on EBay. Glad I did. So far I found a vintage Hot Wheels car that sells for $10 - $30, two other vintage Hot Wheels in the $5-$10 range, an old block building set sells for $15 - $50, old deck of cards unopened $10-$20. Some kind of industrial sculpture that is being shown at an art gallery, no estimate on value yet.
Apparently the people who ran the thrift store did'nt research anything that came in there store on EBay, Etsy, Bonanza, etc. Me thinks I know part of the reason why they went out of business. They were trying to sell used plastic food containers from Walmart and plastic cups from fast food places for more than they were asking for the vintage Hot Wheels!
The bad news (or good), now I have to go back through 4 garbage cans, and 20 boxes of garbage to make sure I did'nt throw away any good stuff myself.
