1-of-1 (One-of-One): A card that is stamped with the serial number “1/1,” signifying that it is the only one of its kind in the world. A  Superfractor is Topps’ most famous type of 1-of-1 card, a parallel distinguished by its swirling gold Refractor pattern.

Superfractor: Topps’ most famous type of 1-of-1 parallel, distinguished by its swirling gold Refractor pattern.
