Copper coins have unique concerns when storing pieces in a collection long-term. The nature of copper makes them often more susceptible to some of the problems that can develop through time such as the development of residues and the creation of irreversible corrosion from that residue. When it comes to conservation, copper coins often present unique challenges in removing detrimental residues yet preserving the natural color of a toned copper coin.
This large cartwheel like 1797 Great Britain 2 Pence was recently submitted to NCS to have centuries of residues removed from the surface. Careful conservation efforts were able to remove much of the offending residues to prevent future damage and to make the coin brighter and more desirable in appearance. This coin was able to grade well with standard numeric grading with NGC following the professional conservation work.
