With well over a hundred expansions printed since 1999, the set symbol is the fastest way to work out exactly which one a card belongs to.
Where to find it
Look at the bottom of the card, next to the collector number. Every expansion gets its own small icon here — Mega Evolution sets like Pitch Black and Phantasmal Flames each carry a distinct symbol unique to that release.
Symbol plus copyright year
The symbol alone can occasionally be shared across a main set and its related sub-products, so pairing it with the copyright line at the very bottom edge of the card gives you an exact year and narrows it to one specific print.
Why it matters for value
The same Pokémon printed across different sets can have wildly different values, so correctly identifying the set via its symbol is often the first step before checking a price on any card, from a Common Goldeen to a chase Rare.
