Vinyl pressing mistakes

I have a mis-labeled Arista Grateful Dead - Histroic Dead album with an Alan Parson's Project label on sides 3/4 of the album (vinyl pressing is still GD). My Goldmine's book doesn't recognize the error, but I still think it is worth something extra.

I have a John Tesh LP, the cover of which is clearly labled: "Contains music"

The mistake is admitting to owning a John Tesh LP, even in jest! :-)

I remember when I first got into vinyl a trip to New Orleans, to go to Jazz Fest. When away i like to check out local vinyl stores. So i happen on this one down in the quarter, a virtual jazz museum. At the time Coltrane was the shiznit for me, especially late 1965 stuff. So I pick a copy of Live in Seattle. When I get back home to put the record on every things fine untill I go to listen to part 2 of one of the songs and I get Africa Brass from 1961. Another example was my father in law who bought a stck of Christmas CD's at the local pawn shop. So we are sitting there enjoying the sounds of the season when the disc changes and out comes Carols Nakai(native american flute player. The label on the CD was marked Liberace's Christmas.
