Which Ian Seymour card is the real rookie card

He debuted with Tampa Bay in June 2025 and his RC-logo cards are 2026 Topps issues: Topps Series 1 #165, Topps Heritage #181 (a short print in the base set), Topps Finest #154, and a retail-only Topps Chrome Rookie Autograph (RA-IS).

PSA

Top grades:: Gem Mint 10, then Mint 9 and NM-MT 8.

Half grades:: Yes, from Fair 1.5 up to Mint+ 9.5.

Authentic (AU) for a genuine card that cannot take a number; Authentic Altered (AA) for one that was altered.

How to identify your Ian Seymour card and check what it sold for

Find the year and maker on the back of your Ian Seymour card, and the card number, usually top or bottom on the back.
Check the front and back for a serial number (for example 23/99) and for a colored or patterned finish: those mark a parallel, which is a different card from the base version.
Look for the RC logo or the word Rookie. A card from before the first pro season, such as a Bowman 1st or a college card, is a prospect card, not a rookie card.
Note any grade on the slab label (PSA, BGS, SGC, CGC). A raw card and a graded one are different listings.
Search sold listings for that exact year, set, number, parallel and grade. What a card sold for is a better guide than any asking price.

Check Ian Seymour rookie cards in eBay's sold listings or eBay's price guide for that exact card.
