Ultimate Silver & Copper with Brass Bang Ring by Johnson Precision Magic

The ultimate in simplicity and mystery. Two coins shown front and back;
a Half Dollar and an English Penny, one in each hand. Hands are slowly
closed and the coins instantly change places. Same effect is repeated
under equally impossible conditions. When the spectator grabs for the
coins, let him. Two coins only are used, so at the finish you’re clean.
Truly a brilliant piece of magic. Manufactured with Johnson Products’
usual attention to quality. Complete with coins and bang ring. Easy to
follow routine included.
