Are most deals done privately? Not for me they're aren't, most of my buys are done through Ebay.
I've never really had much of a clue what records are "worth". I sold large chunks of my collection 12 years or so ago to keep my head above water, and stop the house from being repo'd (again).
Since things have got a bit better, I've been on a mission the last couple of years to get back every record I sold, and bar one or two I've done it. I'm now on a mission to get every record I ever wanted and the Ray Pollard is one of those that was near the top of that list.
Surely a record's "true" value is what someone will pay for it? Not that it matters to me. Unless I hit really hard times again my records will be with me until the end.
