EBay, Collectors, Flea Market & Antiques

Find items I can't find any info on. I pretty much buy to sell and only have a few items I've kept. Some 1960s rock and roll posters and a few things I've found relating to a famous 3rd cousin.
So, I let my wife list them for auction starting at a very low price and see where they go.
My hobby business is mostly for fun and I'm trilled when I do get a big hit. I recently bought a lighted gas station sign for $30 and sold it for $220. it sold the first day in the mall. I do lots of items I find for a nickel to a dollar for $5 to $20. Have sold lots of bottles that way. Records too. I have a tool now that I bought for a nickel that says General Electric on it. Can't find anything on eBay or other sites. I did see lots General Electric items that have value because of the name. Might have my wife put it on eBay or just put it in the mall for $10. I'll keep searching for a while.
Good luck and have fun and keep looking.
