Due to a manufacturing error, only 2,000 of these royal blue "Peanut" elephants were fabricated with a darker color than originally intended. Now, it's the most collectible Beanie Baby in existence, and sells for as much as $5,000. Other valuable versions include Humphrey the Camel, valued around $2,000, and the 1997 Princess Diana Beanie Baby.
The most expensive/valuable Beanie Baby by far is a first-edition Princess Diana Beanie Baby. There are several on eBay, many listed in the six-figure range. The highest one is going for $350,000. | Some Beanie Babies Are Still Worth Something
