Decks of cards or even single cards are also collected as a hobby or for monetary value. Playing cards are available in a wide variety of styles, as decks may be custom-produced for competitions, casinos and magicians (sometimes in the form of trick decks), made as promotional items, or intended as souvenirs, artistic works, educational tools, or branded accessories. The reverse side of the card is often covered with a pattern that will make it difficult for players to look through the translucent material to read other people's cards or to identify cards by minor scratches or marks on their backs.
