if you really want to get an idea of what a record is worth, check out closed auctions on ebay. as my old friend the record store owner said, "it's worth what you can get for it" and ebay tells you what people are actually paying for things. it's been my experience that local used record stores ask a little less than what they could get on ebay, but not if you're talking really valuable stuff. it makes no sense for them to NOT put it on ebay when they get their hands on a rare thing. in fact, a lot of the super rare stuff never even makes it onto the floor of record stores; it goes straight to ebay.
