Hello, Newbie here. I have had a large change jar for about 20+ years and the bottom finally broke out. I found a very interesting 1966 Quarter that may be stamped on the wrong planchet. I took the quarter into a coin shop to gather more details and they said that the quarter may be stamped on the wrong planchet. They weighed the quarter and it appeared to have the same weight as a normal quarter, but advised me to send it in to NGC to have it evaluated. I don't know much about coins, so I was hoping to get some general information/input on this type of coin. Any information provided would is appreciated.
