The Most Valuable Collectors' Items in History

50. David Bowie's 1974 Diamond Dogs Vinyl

Manufacturer: RCA Victor 
Original price: US$ 6.50*
Current value: US$ 3,550.00*

David Bowie is one of the most iconic musicians of all time, and it's no surprise that collectibles bearing his name sell for a lot of money. This is even more true for Diamond Dogs, the artist's extremely rare album. Published in RCA Victor in 1974, Diamond It has six A-side tracks and five B-side tracks.

The reason Diamond Dogs sold for US$ 3,550 on eBay is that the record sold has unique cover art. Only ten copies printed had unretouched covers, so most Diamond Dog records sold looked a little different from these rare and expensive editions.
