If you get a record price guide you will see that there are many factors that go into grading vinyl, which is one of the top determining factors in its worth. The condition of EVERYTHING is taken into account: the record itself, the label on the record, and the cover. Also, whether it's an original pressing or not is taken into consideration. Beatles albums have been issued and re-issued numerous times (all their albums were moved from Capitol to Apple in the mid-70s, then back to Capitol shortly before the advent of the CD). Given their popularity, the only truly rare (and therefore valuable) LP is the so-called "butcher cover" of "Yesterday and Today." Their 45s on VeeJay are also valuable; again, if they are in mint condition.
As for "who knew," all of us who grew up with vinyl! LOL
