rest - https://www.denverpost.com/2018/03/2...-card-auction/More than a year after retiring from the NFL, former Broncos guard Evan Mathis is on the brink of landing a big pay day.
Or a really big house.
An avid memorabilia collector, Mathis is selling a 1952 Topps Mickey Mantle PSA Mint 9 card through Heritage Auctions’ inaugural Sports Card Auction to pay for his family’s dream home. Heritage estimates the card to be worth $3.5 million, which would set a record for the most expensive price ever paid at auction for a baseball card. (The current record is $3.12 million, for Honus Wagner’s 1909-11 T206 that sold in 2016.)
