The Beatles, Yesterday and Today
The Beatles released Yesterday and Today with Capitol Records in 1966, and if you happen to have a copy with the original cover, it's worth upwards of $125,000. The band originally photographed themselves covered in raw meat, but the label thought they needed a more "palatable" look, so they redid the shoot. There are select versions of the meat-clad cover still in circulation, though, and it's worth a ton of money.
The Legacy of the British Invasion
It's hard to quantify the legacy The Beatles left behind. No other rock band has inspired more artists, released more hits, or encouraged so much social reform than these Brits. Before the deaths of John Lennon and George Harrison, the foursome was on their way to becoming the most iconic band in history.
