|Hopping Half (half dollar version)|
A classic coin trick. Show both sides of an English Penny and a U.S. Half Dollar. Repeatedly, remove one of the two coins from your hand and place it in your pocket. Open your hands to reveal both coins are still there.
Then, to knock their socks off, show the English Penny and close your hand around it. Upon opening your hand, the Penny has changed into the Half Dollar.
Requires little skill.
