I buy and sell stuff, vintage/retro/antique and things I like, watches, cues and guitars. Nothing high end yet, but I stop at almost all thrift shops and pawn shops. Most of my pool scores are from the same chain of pawn shops. I've talked to a few managers and many employees, none seem to know cues unless they are production. Some people have the idea that cues aren't worth anything, which makes it easier to buy low. The am and pop pawn shops care about every dime and generally do more research. Other places just go strictly by numbers. If they take in something for $20, the ask $100 and take $70. They made a 250% profit, they are happy.
When I found my Scruggs at a pawn shop, my first inclination was it had been stolen. Then I thought, it is in an old oneil case, one shaft is missing a tip, there is a small amount of rust on the hinges and the case had a slight mildew smell to it. I figured it was somebody that passed and taken to the pawn shop for whatever they could get out of it.
