East Coast Magic manufactured this item many years ago, Nathan Kranzo recently re-released this
The EDM gimmick was manufactured from individual playing cards which makes it undetectable if you look straight at the deck from the side. The newer version is manufactured in a different way which makes it sturdier but not entirely as deceptive (but still good enough with Nathan’s handling). please note that ECM has manufactured this from Tally Ho Fan Back with blue backs. We are including the gimmick as well as a regular deck.
A magician “gives” a pair of invisible coins to their spectators. The magician then takes a small glass and places it mouth side down on top of a deck of cards. The first spectator is asked to place their invisible coin on the glass, and the magician will make coins pass through the bottom of the glass, and when they pass through the glass they will become visible. The magician gives the glass a smack and suddenly an actual quarter appears bouncing around inside the glass. The best part? The magician can immediately repeat the trick with the second spectator.
Invisible Coin comes with a gimmick (blue Tally Ho Fan Back) you can put inside your deck and will allow you to perform the effect right away. We are also including a regular deck to match the gimmick.
The gimmick holds two coins, and works with almost any currency in the world.
There are not springs or complicated mechanical parts that can easily break or misfire.
A very visible effect that is rather easy to master.
Supplied with written instructions, you provide the coins!
