NCS could certainly evaluate your coin for the verdigris and corrosion. On early copper such as yours, many times true verdigris is a protective substance that will prevent further corrosion from taking place. There are many times, however, when what will appear as verdigris is actually active corrosion and that can usually be removed. Removal of any active corrosion will keep your coin stable in long-term storage.

 

Encapsulation in NCS Details Grade of Genuine holders is a recommended option after the conservation.
