Elvis Presley — Speedway (1968)
There was a time in his career when Elvis Presley started to dip his toes into acting. Even though the movie was not well-received by critics, everyone agreed that Speedway music was great. If the rumors are right, they only made 300 copies of the album. You can sell a copy for $5,000!
Brute Force — King of Fuh (1969)
This single barely saw the light of day, thanks to the obscenity in its lyrics. After major supporters did not like it, they chose to soften the songs instead. The record got out after that. It is interesting to hear that they released the record in 2010, nearly half a century after recording. Only a thousand copies of this album got released. It is possible to get $5,000 for a copy of this!
