Contreras Goes Back-to-Back: Champ and Card
Milwaukee takes the Series 4-1, and its backstop's Home Field Advantage card runs the table right along with him.
The Contreras Tax
William Contreras caught the Brewers to a title, and the hobby chased his 2025 Topps Home Field Advantage PSA 10 to $320, up 166.7 percent. That's 559 sales in 30 days. The volume play on the champ was Jacob Misiorowski's 2026 Topps base PSA 10, which moved 5,014 copies and still slid 27.7 percent to $250. Rings don't lift every card equally.

Rays on the Board
Tampa Bay lost in five, but Junior Caminero's 2024 Topps Chrome Update Future Stars PSA 10 climbed 55.6 percent to $62 on 570 sales. Brody Hopkins had a louder percentage move, his 2025 Bowman Chrome Prospect Autograph PSA 10 up 58.4 percent to $125. A short series still left room for Rays prospect cards to breathe.

Caglianone's Sterling Month
The biggest gainer in the hobby had nothing to do with October. Jac Caglianone's 2026 Bowman Sterling PSA 10 jumped 169.3 percent to $99, on 941 sales. That's the kind of volume you usually only see for guys playing in the postseason, and he wasn't.

Devers at a Decade Low
Rafael Devers's 2018 Topps PSA 10 fell to $15, down 71.2 percent on 288 sales. That's a flagship rookie of a star bat trading for less than a blaster box. Carlos Narvaez's 2025 Topps Chrome Rookie Autograph PSA 10 cratered harder at $33, down 79 percent, but the Devers number is the one that makes you stare.
