Copentro (or Visible Coins in Glass) is a marketed trick where coins are made to vanish and then reappear within an upside-down glass on a display stand.
After a version by Bob Kline was marketed in the United States in 1947 as "Copenetro", Hughes would release three different versions of his original routine in England including "Visible Coins in Glass".
- The Coin of Mercury in Modern Coin Manipulation (page 144 see figures 85-88), uses a book as platform for the glass and cover (1900)
- "Coin shooter" by H. J. Burlingame, Sphinx (January 1927), uses a book instead of a wood base.
