Sun and Moon Coin by Johnson.
This beautiful double transposition was devised by Albert Goshman and it appears in Bobo's New Modern Coin Magic. THe sucess of this trick depends mainly on a smooth execution of the "Bobo Switch" and the "Goshman Back Pinch." The Sun & Moon coin consists of a copper/silver insert showing a half dollar on one side and an English Penny on the other, with an English Penny shell that fits loosely over the insert. A regular half dollar is also required for this routine.
