Card number
A card number is the figure printed at the bottom of a card, written over the set's printed total, as in 101/100. It places the card in its set and shows when a card sits outside the main list.
Also called Set number.
In more detail
The first figure is the card's own number in its set. The second is the printed total, the count of cards in the set's main list. A card marked 45/102 would be the 45th card of a set with 102 cards in its main list.
When the first figure is higher than the second, the card sits outside the main list. Pokémon collectors call these secret cards, and the first one appeared in Team Rocket, a set of 82 cards that also holds a card numbered 83/82. Since the Scarlet & Violet set, its illustration rares carry numbers above the total as well.
Check the number against the card's name and set before you buy. It is the surest way to tell apart two printings that look alike, and price guides and sellers use it to identify a card.
