What are secret rare Pokemon cards?

Secret rare Pokémon cards are a special category of cards that are not labeled with a standard rarity symbol, making them harder to find. They typically feature unique artwork, alternative designs, or special foil treatments and are often numbered higher than the regular set, indicating they are part of a limited print run. Collectors value them for their rarity and unique attributes, often making them sought-after items in the Pokémon trading card game community.
