Looks mint state, with a possible old cleaning. The fine granularity visible on the portrait is unusual. If this were a copper coin I'd suspect light corrosion but you don't often see that on silver. The angled photos aren't the best for grading.
The dark tone spots hurt the eye appeal and limit the grade. I'd say the highest realistic grade would be MS-62.
What other coins were in the clock?
