Effect

Place a coin in your hand, calling it a Magic Vanishing Coin. "If I wave my hand over it...like this...it vanishes!" You wave your hand over the coin and it visually vanishes. Your hands are shown all around, the coin is gone! There are no suspicious moves, or sleights. Instead of vanishing a coin, you can make it change into another coin, or shrink to a tiny coin. There are many other possibilities.
