A staggering number of collectors rushed to eBay on Monday night hoping to commemorate the moment baseball’s top prospect made his major-league debut.
The No. 1-ranked player according to MLB Pipeline, Boston Red Sox outfielder Roman Anthony went hitless but drove in a run against the Tampa Bay Rays.
Despite a lackluster debut that included an error in right field, Anthony’s sports card market saw tremendous movement following his call-up from Triple-A Worcester, with eBay research tool Terapeak confirming more than 1,450 sales across Monday and early Tuesday.

At the time of the data’s retrieval by cllct on Tuesday morning, 25 of those sales had topped $1,000 or more, including the $4,000 paid for a 2023 1st Bowman Chrome Prospect Autograph Gold /50 PSA 9.
According to Card Ladder, the record sale for any Anthony card at public auction is the $62,500 paid for his 2023 1st Bowman Chrome Prospect Autograph Superfractor 1/1 in September 2024.
The highest sale for Anthony so far in 2025 is the $39,289 paid earlier this month for a 2023 1st Bowman Chrome Prospect Autograph Red Refractor /5 at Alt.
Collectors were also able to spot Anthony wearing a Topps MLB Rookie Debut Patch on his left sleeve Monday night. That patch will be removed and later placed into a 1/1 card autographed by Anthony.
Anthony’s Rookie Debut Patch Autograph is widely expected to be one of the most coveted patches from the program to date and likely considered his best rookie card in existence — but that card won’t be available until 2026.
