most all lps were sealed using shrinkwrap. Shrinkwrap, surprise, shrinks over time and the results were often warped records. Leaving the shrink wrap on an opened record was generally considered a bad practice. I'd be suspicious of any record that has been sealed in shrinkwrap for many years. The clear benefit of course is that the cover is protected and may be in good shape as a result.
Veracity of albums for sale being "sealed"?
Just wanted your opinions on whether or not the high prices of collectable albums should be so much higher for sealed versus unsealed albums. Could some of these be recently sealed after having been used, by a person with access to a wrapping machine? And how would the prosepctive buyer know? Thanks.
