can you use the penny/dime trick with the raven

I'm not sure. I have both and never thought of it. I think the penny dime uses aluminum, so it wouldn't work... but I may be wrong. But if you have the Raven, you could do this trick with real Canadian coins, or steel core U.S. coins. Just be sure that the smaller coin is fully concealed under the larger one. Funny you asked since when I first did penny and dime for my wife, she thought I used the Raven and got red in the face when I showed her the Raven was still in it's box. But for the price, I totally recommend the penny and dime trick.
