31/50Cards numbered 31/X are the 31st copy produced of their parallel print run. The 31 numerator stays the same across every set and parallel, but the denominator (the X) changes: a 31/99 is the 31st of 99, a 31/25 is the 31st of 25, and so on. Collectors who care about the 31 stamp rather than a specific print run can browse them all here.
For a specific print run, see the combo pages linked above. For broader context on what serial numbers mean, see our guide to serial-numbered sports cards.
A card numbered 31/X is the 31st copy out of its parallel's print run, where X varies by set and parallel. A 31/99 is the 31st of 99, a 31/25 is the 31st of 25, and so on. The /X notation is collector shorthand for "of any print run."
Collectors hunt 31/X cards for a range of reasons: it might match a jersey number, a birthday day, a card number, or simply be a numerator they collect across all parallels. Each 31/X copy is one-of-one for its specific print run.
For any given parallel, the 31/X copy is one-of-one — only one card in the world carries that exact stamp for that print run. Across all sets and parallels combined, 31/X copies exist in larger total numbers because thousands of different cards are produced each year, but each individual 31/X card is unique.
eBay's title search misses most 31/X cards because sellers rarely include the exact serial in the listing title. SerialScout reads the serial number from every listing image and lets you filter by exact numerator. This page shows every active listing with a numerator of 31, across all print runs.
