A Goodwill in Pennsylvania was going through all of their donations and came across a gold LEGO piece. Thinking nothing of it, the piece was originally priced at $15, but as they did more research they found out that LEGO only made 30 of these pieces.
It’s 14-karart gold, and is obviously extremely rare. The store ended up auctioning off the item, where it sold for more than $18,000 which is believed to be the most expensive LEGO piece ever sold!
