The man who first wore the San Antonio Spurs’ Coyote costume has raked in more than $49,000 by selling two of his five NBA Championship rings at auctions. Tim Derk, the creator of the Coyote concept, entertained fans as the mascot for two decades before retiring after a 2004 stroke. Recently, he decided to sell his five championship rings with the help of New Jersey-based Goldin Auctions.
