Pawn Stars is a History Channel show where costumers bring unique objects to a popular pawn shop—The Gold & Silver Pawn Shop—to purchase or reject, based on their negotiations. And as we’ve seen since its debut in 2009, some objects are more unique than others.

In a recent episode, a collector named Nader arrived to sell the suit worn by Christopher Reeve in the 1978 film Superman, along with the crystal Superman used to create the Fortress of Solitude.
