I found an old magic book called MODERN coin Magic by J.B. Bobo and I remember after ...

... reading the Royal Road to Card Magic I didn't care as much for Coinmagoc after learning the first trick: sleight of hand Or ... how to look like you are putting a coin in one hand while actually just keeping it in your fingere rubbing it across your other palm as you sort of pretend to be placing something in your palm while you REALLY keep it in your upper phalanges or space between fingers and so you can make the coin DISAPEAR because people dont know where it really was placed. People CHOOSE to believe something was DEPOSITED . Imagine how many pidegeons the Rothschild had to use to confirm news or napoleans defeat at Waterloo. "Soery sir we cant release your deposits untill we recieve at least 3 confirmation pigeons "
