There is a magic shop not to far from me. I've been in there a few times looking for coin tricks. Lots of 2 headed or 2 tailed coins and of all deniminations. Also, lots of honed out coins where a dime fits inside a cent, nickel inside quarter, etc. It is amazing how many magic tricks have coins or currency in them. I purchased several of these but found due to Arthritis, my attempts to do magic stuff is long gone. Sure would be fun though.
