Diminishing Coin. British, 1950s. Finely crafted gimmick allows the magician to make a coin, held at his fingertips, to diminish in size from a thick five shilling (one crown) piece some six times, until the small coin, a 1p coin, vanishes entirely. Includes wooden shims for storage. Finely constructed and the first of its type we have encountered. With a note indicating the prop was used by Graham Adams, a noted sleight-of-hand expert.
