I received this as part of a gift from my grandfather a few years ago. This coin was not assigned a details grade. Obverse: Reverse:
I think it looks like a fair grade for the coin. I mean, the difference between the grades at this level are highly subjective and almost negligible. F-12 to F-15 is almost like the difference between MS63 and MS64 - Grades are highly subjective and very difficult to apply consistently across highly circulated (non-MS) coins.
