Misfits, Legacy of Brutality (1985)
The band only pressed 16 copies of it during its second run. However, singer Glen Danzig quit the band and then pressed, overdubbed, and produced the compilation album. He also overdubbed the instrumental portion to avoid paying his former bandmates royalties. A mint copy is worth $5,000!
Elvis Presley — Speedway (1968)
His acting days were nearly over when Elvis did Speedway. The film flopped with the critics and at the box office. Despite this, this soundtrack album is still worth a fortune. According to rumors, they only made 300 copies of this. If you have a mint recording in the original packaging, it can go for $5k.
