Among the most valuable records of all time is a release from the legendary Sun record label in Memphis. “Lonesome Old Jail” with “Greyhound Blues” on the flip side was recorded and released in 1953 by Blues artist, D.A. Hunt. For 50 years it was thought that the record was only available as a 78 but a 45 version is now known to exist. The 78 rpm record is worth up to $5,000.00 but find an original 45 and you’ve hit the jackpot. An original copy can sell for $40,000.00 today. Re issues that are not collectible do exist.
