Serial-numbered parallel cards are limited-edition versions of base cards with a number printed on the card indicating its place in the print run — for example, "47/99" means this is copy number 47 out of a total print run of 99. The lower the print run, the rarer and more valuable the card.
Serial numbering creates verifiable scarcity — unlike older "rare" cards where print runs are unknown, a numbered card comes with a built-in provenance statement. A /10 card is genuinely rare because there are only 10 in existence. This scarcity creates a direct relationship between print run and value.
