In order to determine the rarity of a given Pokémon card, it is important to examine the symbols present on the card's face. Specifically, a black circle signifies a common card, while a diamond indicates an uncommon card. A star symbol denotes a rare card, and should be noted accordingly. Furthermore, if a card has a single black star that displays the word "promo," it is likely that it was included as part of a booster box purchase. Additionally, if a card features two golden stars, it is classified as a secret rare card. This information can be invaluable for collectors and enthusiasts seeking to identify and evaluate various Pokémon cards in their collection.
