On the reverse, we have the denomination, "1 skilling". "Danske" means "Danish". "KM" is short for "koppar mynt", meaning "copper coin", then the date 1771.
On the obverse, we have the crowned monogram of the king of Denmark at the time, Christian VII: a double-overlapping letter C and numeral 7.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
