Hi, I am going through my inheireted coin collection and recently and found this nickel. He more so collected change over the years and and had a ton of modern FV coins and so after picking out all the silver and older coins worth more than FV I took all the rest to coinstar and this one was rejected. I was wondering if it was a error coin. The closeups of the reverse it almost looks like it is an oversized planchet that got stamped over another nickel and encased it. The obverse looks like it is pushed down too much. Any input would be appreciated.
