1990 D Dime RPM Verify

rbaker20, outside of cents, I have heard there are RPM's beyond 1989 (did not know the nickels were included in the 89 stop). That being said, I have little or no information to give you about this. There is evidence in your pics that this is nothing more than Machine Doubling. The pics could be better to tell for sure, but I have marked up one of your pics to show you what I mean. When you have different devices showing movement in the same direction, it is usually MD and the mm looks smaller than it should if you take away the doubling, which is another symptom of MD. The inside of the ear may be from lighting but the area I have marked up in the upper ear, I do not believe is from lighting, just MD. See what you think.
