The Mint

When a card is graded a 10 for the very first time on Holobrook, that slab becomes its POP 1: the only one of its kind. Each card has three to win, one each for PSA, BGS and CGC, and once a POP 1 is taken it belongs to that player for good. 230 have been won so far, 97 by named collectors. Slabs go on show under their collector's name; ones kept private still count as taken and appear small and grey.

POP 1

The first 10 of a card from one grading company, across every player. Three per card: PSA, BGS and CGC. All of them are on the Every POP 1 tab.

1ST ED #3/10

One of the first 10 slabs graded from a new set, any card and any grade, numbered in order. Opens for 90 days after each set's release.

MY FIRST

Your own first 10 of a Pokémon. Everyone can earn one for every Pokémon, so these never run out.

FOIL

A holographic label that turns up on about 1 in 40 slabs, at random.
