This is a beautiful 2020-21 Black Diamond “Run for the Cup” Nathan MacKinnon insert card, serial numbered 87/99. Part of Upper Deck’s high-end Black Diamond release, this card is printed on premium foil stock with a bold die-cut design and acetate overlay — a true standout in any collection.
Only 99 copies of this card exist, making it a Super Short Print (SSP) insert. Whether you’re a MacKinnon fan, an Avalanche collector, or a hobby investor, this is a great addition to any hockey card collection.
