Hi, my dad recently passed. He left me his 1962 Olympic white. He had it authenticated, but I’m going to have to do that again because I don’t know where that is. Where would be the best place to sell it? I’m very sentimental about a lot of things but not this guitar because he never played it. He was a bass player. Any advise? Is there a certain authentication I should be looking for? I know with diamonds, for example, you’d get it evaluated by GIA. Is there an equivalent in the guitar world? Are there vintage instrument auctions? In the vintage auto world, for a high dollar vehicle, you look at mecum or Barrett Jackson auctions. Is there something like that for instruments? I’d really appreciate any help I can get. I know nothing about this sort of thing.
