The Super Spellbound – Toshio Akanuma / Tricks Co. ESTATE

Good used condition. A blue poker chip changes its color to green by rubbing briefly. There is another rubbing and the green poker chip changes back to blue. The sequence is repeated; spectators begin to wonder about the other side of the chip.

Now the chip is openly flipped, and the other side is revealed as half a dollar!! Then the half dollar is turned over, and the other side is changed to an English half penny, which can eventually be shown on both sides.
