William Contreras, Jacob Misiorowski cards surge after title run

William Contreras cards heat up after World Series MVP run

William Contreras entered the postseason as one of the most collectible players in the game, and his stock climbed even further after Milwaukee's World Series victory. The Brewers catcher, 28, capped the championship run by winning World Series MVP honors, batting .381 while throwing out four would-be base-stealers and helping manage the game with the automated ball-strike challenge system.

The title was Milwaukee's first in franchise history, adding another layer to the surge in interest around Contreras cards. Collectors have responded quickly, with several of his key issues jumping from prices that had often sat well below $1,000 to four-figure sales during World Series play.

Contreras is already known for a strong hobby profile, and the latest run has pushed demand even higher for premium autographs, low-numbered parallels, and one-of-one cards.
