Tommy Johnson, Alcohol And Jake Blues (1930)
In the world of music, speak about a real gem! This record was found in North Carolina, solely by chance. On eBay, the seller then added it for sale and was surprised by the response. There are 2 documented versions in nature, and both of them belong to John Tefteller, the victorious bidder. He paid 37,000 dollars for that!

Prince, The Black Album
He wanted to stop it not long after Prince launched ‘The Funk Bible,’ and charged the record company to recover all the albums. Apparently, he felt that the album was ‘negative.’ But, as every single was pirated and aired on the radio, it did not succeed. Prince had a more change of heart in the end and published it on CD in 1994. In 2018, $42,300 was obtained from an initial and unopened American press. In the meanwhile, a Canadian unsealed duplicate went for $27,500.
