Awhile back I posted a few pics of an 1839
Half Dime in about MS61-62 condition. After careful examination with a microscope, it appears atleast three of the stars surrounding the seated liberty have noticeable doubling and very noticeable doubling on the 9. Pretty much sure it is
Machine Doubling but I was wondering how many varieties exist for this date and if anyone could help attribute it. My camera returns from being rebuilt tomorrow so I'll get some close ups posted then.

Thanks
