This illustration shows the manner in which the fake coin is hid in the penny shell. Especially when the envelope is marked “Snug Fit” it is sometimes necessary to tap the shell several times before the coins will come apart. If the coin is very snug or tight, shake it in a glass to separate it. With the mechanical coin a great number of bewildering and mystifying tricks can be accomplished. Only a few of the stunts you can do are described, as you will find it very easy to work out many entertaining deceptions of your own.
