I have the chance to pick up some Beatles LPs in NM condition. He wants me to give him a price I think is fair for both. I started to look up prices on the net but it was a jungle and I don't have very much info on them. All I have to go on is this: Help: PCS 3071, UK Rubber Soul: PCS 3075, UK Revolver: SW 2576, Canada Sgt. Pepper's: SMAS-2653, Canada Abbey Road: SO-383, Canada The Beatles Again/Hey Jude: SO-385 What is a fair price on these and is it enough to find out the value with just this info?
