Being a pack rat does have its advantages if the stars are properly aligned – take Tanner Sandlin’s case for example. He forked out anywhere from $5 to $10 when he was a 10-year old kid for the Air Raid Atari 2600 videogame, only to realize that it fetched a $31,600 price point on eBay when it was placed for auction a good 20 years later, making this the second most expensive video game ever sold over eBay. The main reason behind this? There are only 13 known copies of the game around today (talk about lucky 13!), with Tanner’s copy coming in an original box.
