Coin through Card (Half Dollar)

Two half dollars and a playing card are displayed. A stem glass is introduced and shown to be empty. The card is placed on top of the glass. The two half-dollars are picked up and dropped on top of the card. Instantly and visibly one coin penetrates the card and lands in the glass. Two very special gimmicked coins and a gimmicked card make this miracle possible without any sleight of hand.
Wine glass not included.
