How do I know if my Pokemon cards are worth money?

How do I know if my Pokemon cards are worth money? Every Pokémon card is stamped with a small symbol in the bottom right corner that identifies its rarity. As is the case with most collectibles, scarcity is a major factor in determining the item’s value. So the rarer the card’s marker, the higher value it’ll likely command at auction.
