Lots of magic for the money!
An easy, astounding trick that can be presented in a number of ways! This one is a lot more sophisticated and clever than you may think.
It's simple: you place a regular coin on the base, then cover it with a top that has been previously shown to be empty. You can make the coin vanish, change into another denomination coin, change into a small note, or magically turn itself over. All you have to do is cover the coin with the top, snap your fingers (for magical effect!) and take the top off- the magic has happened that quickly and easily!
You can use the Coin Pedestal as a coin production, or to switch coins for mentalism tricks as a way to produce the coin with the predicted date!
