While the Copper/Silver Transpo isn't a new effect, "Digital Dissolve" add an element to it that makes this version stand out among the rest. Steve Dusheck has tweaked this effect to turn it into an instantaneous miracle in your hands.
Watch the demo video and you'll see how fast this happens. Literally in an instant the English penny becomes the half dollar right before the spectator's eyes. And as soon as the transformation occurs you can drop the coins into the spectator's hands and they can examine them all they want to. There is only one move involved and it's really easy to learn. Once you get it down you'll be performing this effect over and over again.
I keep this one close, and I often just do the effect for myself--and it still gets me even though I know how it's being done! That doesn't happen often. It's so strikingly visual that is just begs to be performed.
The coins are high quality, and the gimmick needed looks like it will last forever if treated right. The instructional DVD gives you everything you need to know about the effect and the move involved. It also helps with ideas for the clean up at the end. If you're into coin magic or just want something to sprinkle into your routine that's different from cards but you don't want to spend days learning the sleights, this is something you must own.
