Hello, I am cleaning out some boxes of what I consider bulk that I have accumulated over the past few years buying collections and storage lockers. This product is a bulk lot of over 5500 baseball cards mostly from the 80s/90s and 2000s and weighs over 20 pounds. The cards are standard size and feature players from Major League Baseball (MLB) including but not limited to Frank Thomas, Raul Mondesi, Joe Torre, Barry Bonds, and more. The cards are from a variety of sets and are made of card stock. There may be vintage sprinkled in but I'd say most after 1980.
