Have a coin palmed in the left hand, and borrow a similar one from the audience, and have it well marked (always have coins marked where possible, "to prevent changing"). Make a movement as though you placed the marked coin in the left hand, but in reality palm it. At the same time, open the left hand, and the coin that has been snugly concealed there will look as if it had just left the right hand. By this means a change is effected which you can utilise according to circumstances. By fidgeting about among the audience, you may be able to place the marked coin under one of them; the other coin being held by someone who is directed to hold it "very high, sir, very high, so that everyone can see it"—the real object being to keep him from examining it too closely. By standing the holder of the coin on a chair, an opportunity for slipping the palmed coin into his pocket presents itself, and should be taken advantage of. The marked coin being once safely hidden, it is an easy matter to palm the unmarked one (which, of course, the audience has been led to believe is the marked one) and make it "pass" invisibly to wherever the other may be. The conjuror's own coin should always be provided with a very distinct mark—a cross is invariably a safe one to employ—as it is rarely that one meets with people who can refrain from instituting an illicit investigation so soon as the conjuror's back is turned. When the holder of the coin is seen to be surreptitiously examining it for the mark, the conjuror should not prevent him, but call the attention of the audience to the fact, and ask if the mark be visible. The holder, seeing the cross, will answer in the affirmative; he not being aware, of course, that the borrowed coin was possibly marked with a very different sign. This incident will add to the effectiveness of the trick.
In tricks a and b the wand will be found very useful. It should always be carried under the arm, after the manner in which soldiers carry their canes; and when any palm has been effected, and the coin has to remain concealed in the hand, the wand should be taken in the hand containing the coin. Beginners, especially, will find this of great assistance, as in the case of a somewhat defective palm the coin can be pressed well home by clenching the wand hard. Besides this, the fact of carrying a wand in the hand keeps the idea of the coin being there from the minds of the audience; and the mind is what the conjuror has to deceive.
