I don't know of any miss-pressings that had a high collector value. The only error I know of that increased the value of a record slightly are copies with the wrong track listing on the jacket of "Kind of Blue." This was restricted to the earliest of pressings befo the error was found. I have a mono recording with this error.
I have a two record set with the side order messed up. Apparently someone put side 1 and side 3 together (no it was not an automatic sequencing record) and side 2 and 4 together so I had to right the correct side on the label area or I would never be able to figure out what side to play for the few tracks I wanted to hear.
The weirdest record I have is by a small but usually high quality classical label (I believe it is Argo) where one side plays back at a totally wrong speed--it is not 33.33 or 45 or any other common speed. When the lacquer was cut, no one bothered to actually play back a test pressing to note any problems and they simply let the problem pass all the way to the final product. I did not even think this sort of thing was possible.
