As I learn more about coins I think I can safely say I can detect an obviously cleaned coin...however, I am curious if this 50 franc piece looks cleaned? It slightly confuses me because it has some cartwheel mint luster, which I tried to photograph, but many (many) scratches in the rather large fields, which are more evident in the photo. In my limited experience, cleaning with a brush does not remove toning from small crevices, etc.
Is this coin likely cleaned or heavily circulated?
Any thoughts would be very welcome!
