12. Royal Blue Beanie Baby
The cute little animals stuffed with bean-shaped pellets, came to us in 1995 (and are, by the way, the reason eBay was created). They eventually became a craze in 1997. The Royal Blue Peanut the Elephant was actually never supposed to be produced (it was a factory mistake). "Peanut" was intended to be a much lighter blue. However, 2,000 of these babies were manufactured with a royal blue pigment. These little buggers are now going for over $3,000! Side note: This is actually not the most expensive beanie baby. There were a small number of hand-stitched Princess Diana Beanie Babies created, which are now selling for over $500,000. That's right, over half a million dollars!
