What a clever idea this is from one of the original coin masters: Eddie Gibson. The amazing Zambini Box! You show the box with the pound coin stamp in the two halves and you add one of the blank brass disks and after a suitable gesture you open the Zambini Box to show the disk has now been transformed into a bonafide coin. Looks great and easy to do of course. Comes complete with all the coins you need to perform the effect out of the box.
