Old tennis rackets like these?

I'm not an expert, this is more of an opinion. I'd assume they would have to be rare or unique rackets and in mint condition. I'm not sure if those are or not. I frequent a lot of thrift stores and there's always old wooden tennis rackets like this. My brother also used to collect them. The ones I've seen have not been worth much at all.

I see these down Cape Cod in antique stores semi regularly. However they look like they move for anywhere from 50 - 100 depending on the racket. However we have the market looking for these and its in person.
