Abstract
A coin magic device is disclosed which comprises a coin holder in which a coin is to be set, and a case into which the coin holder is to be introduced. The coin holder has formed on one side thereof a concavity which has a through-hole formed in the bottom thereof and in which the coin is to be set. The case has formed on the inner surface thereof a guide wall to guide the coin moving inside the case. The coin is set in the concavity of the coin holder. They are introduced into the case. When a key is inserted through the case from one of the slits in the case, the coin is moved from a set position to a offset position as guided by the guide wall. Thus, the key can be inserted through the slits in the case and through-hole in the coin holder, which will give the audience an illusion that the coin is pierced with the key.
