The first live auction collaboration between Fanatics Collect and Sotheby's will be at the end of this month (called "Holy Grails"). One of the cards that will be up for auction is a Brady Rookie Card that is owned by the legend himself (2000 Upper Deck 0685/1250 PSA 10 Auto). It is estimated to go between $160K - $180K.
You can check the rest of the auction items for this collab in the link below. It includes a lot of high profile cards, such as a 52 Mickey Mantle, a Kobe Bryant Ultimate Signatures card, and a Upper Deck Exquisite Lebron James.
