I was curious to know how to get an appraisal of records that are pre-beatle era etc. Some are mostly duds but like the Doors, Beatles, Monkees, Beach Boys, Ettc. Are they worth something? Most likely to fill a space in someone's collection rather than just buying a old chair cause it's an antique.. Maybe I need to know what a person wants, then I can see if I have it. Thanks .
