Davenport’s Improved Kunard’s Coins Trick

This is a well made pocket trick from the 1940s. The magician shows a threepenny bit which is resting on a small wooden block. When the magician passes a second wooden block over the coin, it mysteriously changes to a farthing. The block is again passed over the coin and it becomes a sixpence. Finally this coin vanishes. The blocks may be examined. Complete with instructions. Another example is N2405.
