Why his number matters for cards
A serial-numbered card whose copy number matches the player's jersey number is a jersey match, one of the most recognized chases in the hobby. A Mahomes numbered 15/99 is his jersey match: one specific copy in that print run, and the one serious Mahomes collectors want most.
How to find a Mahomes jersey-match card
The catch: sellers almost never put the serial number in the listing title. They list "Patrick Mahomes Prizm /99" and leave the actual copy number in the photos, so searching titles for "15/99" turns up very little.
Serial Scout reads the serial off the listing photo, so you can search Mahomes by an exact number and jump straight to his 15 jersey matches instead of scrolling past hundreds of ordinary numbers.
