Very nice find, she is in great detail for that old of a copper. There are many opinions as to clean or not to clean. For me I get pretty aggressive (from most peoples thoughts on this subject) Basically I like to decide from what kind of coin I have and what it's possible value might be. I like the hot peroxide cleaning method, it does not hurt the coin just leaves what is really there. Sometimes dirt and corrosion enhances the actual detail of what copper is still left.
In my opinion, it's your coin, your decision as to how you want to clean it or not clean it.
