The first version of this effect was released by Floyd Thayer as Coin Go c. 1926. However, as far as I can ascertain, that version was permanently attached to a palming coin rather than the gimmick provided here, which can be added and removed in an instant and works with many coins.
This version is a great gimmick that works perfectly. I had something similar when I was a teenager in the UK, but this gimmick is 90% smaller and just as reliable. It works perfectly with half dollars and probably quite a few other coins too.
You can borrow a half dollar or use your own that can be examined, and it takes but a second to be ready to go. Then whenever you want you can vanish that bad boy, and look like a pro sleight of hand expert. The audience will have no clue. One of the other nice things about this gimmick is unlike The Raven it works with normal half dollars.
