So today as I was going through my pocket change looking for interesting coins a 1994 United States Quarter Dollar that bears a Pennsylvania mint mark fell out of my hand and hit the floor. I noted it sounded almost like a token when it hit the floor. I then compared that sound to a 1995 Denver 1998 Pennsylvania and even a 1964 silver quarter and none sounded anything like it. Does anyone know if the mint tweaked the composition of the Quarter in 1994? My first thought was that it was a forgery but it seemed unlikely that such a low denomination would be worth the effort. Anyone got any knowledge on this?
Thanks
