Hopping half by Oliver Magic (standard set)

Both sides of a Coin and another coin are shown. You remove the coin from your hand and place it into your pocket but when you open your hand, both coins are still there. You remove the other coin from your hand and place it into your pocket and again, when you open your hand, both coins are still there. Once more you remove the coin from your hand and place it into your pocket but when you open your hand both coins are still there. Now you very carefully remove only the the other coin from your hand, showing both sides as you place it into your pocket but this time when you open your hand, both coins are gone.
