The idea to use a bulldog clip as a switch device is credited to Bob Ostin c. 1953. See Bulldog Switch Clip for more details.
Along comes the inventive Steve Dusheck c. 1981 and takes Bob’s idea to the next level by introducing a half dollar that visually changes into two quarters as it drops into the spectator’s hands. Howie + Bob reintroduced this wonderful item through The Trickery c. 2002 with Steve Dusheck’s permission.
This is a really perfect piece of magic to watch!
