Coin magic is the manipulating of coins to entertain audiences. Because coins are small, most coin tricks are considered as close-up magic or table magic, as the audience must be close to the performer to see the effects. Though stage conjurers generally do not use coin effects, coin magic is sometimes performed onstage using large coins. In a different type of performance setting, a close-up coin magician (or 'coin worker') will use a large video projector so the audience can see the magic on a big screen. Coin magic is generally considered harder to master than other close-up techniques such as card magic, and is one of the least performed forms of conjuring. Coin magic requires great skill and grace to perform convincingly, and this takes a lot of practice to acquire.
