Eddie Gibson was an expert coin maker in Great Britain. This is in excellent condition with English instructions.
With these precision-made coins you can do many effects and here are just a couple:
Drop a half dollar and a quarter in a handkerchief. Pick up the four corners of the silk — and although your spectator just saw the two coins plainly in the hank, without any sleights you pick off the quarter from the outside of the bottom of the handkerchief. The silk is opened, and it contains only the half dollar. This is coin workmanship at its best and is all self-contained. All the necessary coins to do the miracle.
Two coins are shown, a quarter and a half-dollar coin, and any ordinary glass tumbler. The glass is held in a horizontal position, parallel to the body, with the base of the glass pointing away from the body. In actual fact, the hand is around the glass, the fingers curled over the top with the thumb below and more towards the base of the glass than the mouth.
First the quarter, then the half-dollar coin, are placed in the glass so that the larger coin slightly overlaps the smaller coin. Both coins are placed as near to the mouth of the glass as possible. All set. The glass is tilted to an upright position, mouth uppermost, and both the coins slide and hit the bottom of the glass. Then an amazing thing happens. It appears that one of the coins somehow penetrates the bottom of the glass and falls out onto the table. The remaining coin is tipped from the glass and tossed into the air, proving that nothing remains in the glass, which can be passed round for examination.
