A 14-karat gold LEGO piece, which was donated to a Goodwill store in Pennsylvania, was originally priced at $15 but ended up selling for more than $18,000. Goodwill officials say workers at the Du Bois store were sorting through a bag of donated jewelry from the Goodwill store in State College when they found this LEGO piece, a small Bionicle mask. The item was originally sold online for just $14.95. Experts have examined the product and found it to be an extremely rare Kanohi Hau mask. LEGO only made 30 of these golden masks. Goodwill auctioned off the item and sold it to an anonymous collector for $18,100.
