If I remember, Ricky Jay is also a Master of Coin slight of hand.
In 1980, I was working in Springfield Mass. I walked home every evening. I would pass a small Magic Shop and stop in often. Always a bunch of magicians hanging out that were only too happy to put on a show for you.
One night, a guy put a dime in my right hand. I put on left index finger on it before I closed my fingers around the dime and then, pulled my finger out.
I watched as the magician put the nickel in his hand and closed his fingers.
He bumped my right hand with his. He told me to open up my hand. I was holding the nickel and he, the dime.
Still kick myself in the butt for not buying that trick.
