Two Copper & One Silver by Johnson Precision Magic

The standard copper/silver transposition trick given a new face, making
any explanation virtually impossible. This is exactly what the
spectator sees: Three coins are shown - a Half Dollar, English Penny,
and a 20 Centavo piece. Nothing else. The two copper coins are placed
in one hand. There can be no suspicion because the spectator can see
and hear the copper coins in your hand. Magician closes hand and
immediately opens it to reveal the half dollar. Copper coins are tossed
onto table, having appeared in your other hand. The effect is
repeated. The copper coins are picked up and placed into your pocket as
your other hand closes around the half dollar. Instantly your hand is
opened revealing the two copper coins which are tossed onto the table as
the half dollar is removed from your pocket. Everything can be
examined with a magnifying glass at the finish. A truly remarkable
transposition that will leave your audience utterly spellbound. Easy to
follow routine included.
