Copper Sandwich Pair. UK: Eddie Gibson, 1977. Lid is removed, and the brass box is shown to be empty. Three coins are placed in the box: two five-cent coins and a dime. The lid is replaced and the box picked up between finger and thumb. A spectator is requested to tap on the lid of the box. He does so, and immediately one coin penetrates and falls from the base of the box ? the copper coin. The lid is again removed, and the two remaining coins are tipped out. Two copper sandwiches, one regular size and one half-dollar size. Very good. Largest 1 ? x 1 ??.
