I have a 1963 D Franklin Half with some doubling on HALF DOLLAR what kind of doubling would you call it? Any help is greatly appreciated.
I'd say it is ejection damage because of the way the edges are pushed up - and all in the same direction.
You have a coin with Machine Doubling. For more information on this type of doubling and Doubled Dies, go to... http://www.geocities.com/NCADD/educational1.html Ben
