Mr. Gold has been found, and on eBay happens to be as costly as gold.
The current Series 10 of the Lego Collectable Minifigures features a new super rare figure. For the first time Lego has packaged 5000 limited gold (plastic) minifigs randomly worldwide. When the series was first spotted about a month ago no one had a clue exactly how these figures would work.
And, work they do. The first Mr. Gold figures are up for sale from $500 to $1300. Wow.
ToysNBricks has a great write up about said figure, and even does some math about weather or not the investment is worth it.
