Steam Trading Cards are virtually collectible cards you get by playing games on Steam. Card drops are random and only half of a deck is obtainable through drops. Once collected, an entire deck can be crafted to earn Steam Profile Backgrounds, Steam Chat Emoticons, Coupons and Steam XP. Rare foil cards can be obtained if the player has achieved Steam Level 10. Any items that are received from crafting a deck is tradable and marketable, except coupons which are only tradable.
