Superfractor
Also known as: Super, Gold Superfractor, 1/1
A Superfractor is the rarest parallel in Topps Chrome and Bowman Chrome products — a 1-of-1 card (meaning only a single copy exists in the world) featuring a gold chromium, ultra-reflective finish. Superfractors are the ultimate chase card in modern products. A Superfractor of a top rookie player can sell for tens or hundreds of thousands of dollars. The term is so synonymous with 1-of-1 cards that collectors sometimes use "Superfractor" to casually refer to any 1/1 card, even those from other brands.
