Cut Case

From BaseballCardPedia.com

Cut Case: A cut case was a distribution method employed by Topps to liquidate surplus cards. Topps sold cut cases staring in the mid-to-late 70s up until the early 1980s. Cut case cards were cut directly from the sheet and stuffed by machine into a plan brown box -- hence the name. A typical cut case holds around 8,650 standard-sized cards.

Unopened cut cases are extremely rare. Like vending boxes, cards from cut cases are extremely desirable as they did not go through the normal packaging process, are free from wax and/or gum stains, and in many cases were never touched by human hands.
