Many years ago when I was working at Market Magic Shop, I used to demo and sell a trick called Silver Extraction. The effect is you take a half dollar and it ends up turning into a blob of silver and a clear coin. Then at some point someone made a coin that was just the copper center of a half dollar. I don’t know what the routine was, but I’m going to assume it was a similar effect.
I always thought it would be great paired with the blob of silver that came with the Johnson Silver Extraction. Unfortunately they stopped making the Silver Extraction a long time ago, so that was something I never did. Well, recently I came across one of the blobs of silver and bought it.
Now that I have the two of them, I can try it out!
