This photo combination made with images provided by Heritage Auctions shows the front and back of a copper and silver 1792 experimental penny that sold at auction in Schaumburg, Ill. on Thursday, April 19, 2012. Officials with Heritage Auctions say Kevin Lipton of Beverly Hills, Calif., bought the penny on behalf of a group of unnamed investors for $1 million and must also pay the auction house's 15 percent commission. It was never actually put into circulation and only 14 examples of the coin are known to exist. (AP Photo/Heritage Auctions)
The unusual coin was auctioned off Apr. 19 at the Renaissance Schaumburg Convention Center in suburban Chicago.
