Magic Tricks

I was astonished to find that after joining the smaller copper coin to the half dollar shell to perform the disappearance of same and to reveal a "complete" half dollar there is an OBVIOUS copper ring around the base or head side of the shell. Didn't and doesn't make any sense to me and after contacting penguin they informed that this is how the product is. Because of the glaring ring of copper on the SILVER half dollar it is impossible to have inspected which really defeats the purpose of the effect. I DO NOT recommend.
