‘When Collectible Exchange was hired to remove seats and other items from “Old” Yankee Stadium in 2009, it was able to recover 20,000 pieces of memorabilia. Much of which was then put on sale and some items remain unsold 17 years later. But, that is not the case with “Old” Highmark Stadium, where Collectible Exchange was able to garner more than 25,000 items, with most sold or under contract to be sold. The Bills Mafia response has set a new benchmark for the harvesting and sale of items from sports venues. To date, they have beat the Yankees’ ‘Bleacher Creatures’ by 25% – and counting. “The love the Bills Mafia has for anything connected to the team is second to none,” said Brandon Steiner, Collectible Exchange CEO. “I knew they were loyal, but not to this extent. It is beyond anything I have seen.”
