EBay, Collectors, Flea Market & Antiques

They were lots of collectors 30 years ago. But most were old guys that liked to tinker with them. They are dying off now and not many looking for them now.
Not to say they might make a come back some day.
For some reason, I like to pick up old match books with advertising on them. Use to be free everywhere. I keep thinking they will be collectible some day. Old phones have kept some value over time. So, I grab dial phones whenI see them cheap and they sell fast for me.
When I had a store, I had a box full of old door knobs and would hardly ever sell any. One day a lady came in and bough 6. After that more and more sold. Found out Martha Steward had a story about making coat hooks out of them.
