Anyone recognize this planchet size?
I came across this dime in a collection of dimes that had been set aside for quite awhile until I had time to research. Now that I am retired, figured it was about time. It is a 1983 D Roosevelt Dime on an offsized planchet. The diameter is 16.72mm with a well formed very symetrical rim and no reeding. The weight is only 2.0 gr. The color is off as well, medium grey and has no luster, but is very sharp in its detail.
I have been looking for potential foreign planchets and have not found an exact match; some close, but not matching both.
Any thoughts are welcome.
