Atari Cartridge
While reading up on valuable video games, Texas resident Tanner Sandlin was surprised and delighted to see that a game in his collection was worth a lot of money. Sandlin had bought “Air Raid” for the Atari 2600 years prior at a thrift store, paying somewhere between $5 and $10, without knowing its true value. When Sandlin sold the cartridge, he earned $31,600 from his accidental investment.
