BrickEnvy

These days, Lego sets seem bigger and more expensive than ever, but the most expensive Lego of them all never actually hit store shelves.

From around 1979 to 1981, select business partners and Lego employees (supposedly two per year) who worked 25 years at the brick-building factory in Hohenwestedt, Germany, received one heck of an anniversary gift: a 14-carat gold Lego brick that weighs 0.8246 troy ounces.

The rare brick -- a standard 2x4 piece -- somehow came into the possession of BrickEnvy, a small e-store that sells collector-grade Lego sets. The store currently lists the pure gold Lego piece for a whopping $14,450, noting that only a few of these items exist around the world.

To top off the experience, the brick comes in a special original ring-size box with a velvet interior and the old Lego logo embossed on the interior fabric.
