Trading Card Glossary: 50 Terms Every Collector Should Know

Trading card terms can sound like a secret language, but most of them describe just a few things: how rare a card is, what condition it is in, how it was packaged and how it should be stored. This glossary explains 50 of the terms you will hear most often across Pokémon, other TCGs and sports cards, grouped alphabetically so you can find them quickly.

A to C

• Alt art – an alternative artwork version of a card, often with a scene that extends across the whole card.
• Autograph – a card signed by a player or artist, either on the card or on an attached sticker.
• Base set – the core, numbered cards of a set, excluding special extras.
• Booster box – a sealed display box containing a fixed number of booster packs.
• Booster pack – a sealed pack of randomly assorted cards.
• Bulk – large quantities of common, lower-demand cards, often sold by the lot.
• Centring – how evenly the artwork sits within the borders; a key grading factor.
• Chase card – the most sought-after card in a set, the one everyone hopes to pull.
• Crease – a fold line in the card stock; it heavily reduces condition.

• Foil – a shiny, reflective finish applied to part or all of a card.
• Full art – a card whose artwork covers the entire face rather than sitting in a box.
• Gem mint – the top grade from most grading companies, meaning practically flawless.
• Grading – sending a card to a company such as PSA, CGC, Beckett or ACE to be assessed and sealed with a condition score.
• Hit – any special card pulled from a pack, such as a rare, autograph or numbered parallel.

T to W

Putting the terms into practice

Condition terms matter most when buying and selling, so read our guide to Pokémon card conditions before you trade. If you are wondering whether a card is worth slabbing, see should you grade your Pokémon cards. For the storage terms, our guides on sleeving Pokémon cards and side-loading vs top-loading pockets explain the practical differences.

When you are ready to organise, a 9-pocket binder is the simplest home for singles, sets and trade stock. Our 9-pocket binders include the Sleek, with side-loading pockets and fixed pages, and the Dragon Zip, with top-loading pages on a D-ring.

Conclusion

You do not need to memorise every term at once. Bookmark this glossary, and the next time someone mentions pull rates, whitening or a pop report, you will know exactly what they mean.
