• Show two coins, one gold and one silver.
  
• Stick them in your closed hand.
  
• Remove one and place it in your pocket.
  
• Open your hand and both coins are still there!
  
• Repeating this several times, the coins continue to magically reappear!
  
• Finally your hand is opened and both coins have vanished!
  

The effect is real simple and easy to perform.
