It's quite common to misplace LEGO pieces around your home and forget about them, mostly because they are cheap and easily replaceable, but a silver LEGO piece is something you can't easily replace.
Created by designer Jonathan Brady, this LEGO-inspired block piece toy is made with .925 sterling silver. The metal-made toy has joints that can be moved, similar to regular plastic LEGO pieces. It's made from eight pieces of solid metal, which are held together by small rings. The metal toy is also compatible with regular plastic LEGO pieces -- so you won't have to send a fortune to build a silver house for them.
If silver isn't your type of element, you can also get a 14 karat gold version that cost $4,250 or a platinum version that cost $9,500.
