Magic Demo: Coin Base

Here's an easy trick that's often found in beginner's magic sets as well as sold on its own. In the trick, a "base" is shown to be empty. After placing a cover on top, a coin magically appears, seemingly out of nowhere. This trick is particularly good for young kids and it's also quite inexpensive.

Here's how it looks.

You show the coin base sitting on a table as well as a lid in your hand. If you like, the base can be examined and spectators can clearly see that there is nothing in the lid.
