France
Louis XVIII Franc 1822-A MS64 NGC, KM709.1. The sporadic rainbow tones that surround King Louis make his portrait seem life-like. His effigy is a light gray and the remainder of the glistening patina (on the reverse as well) is surrounded by derivatives of amber ranging in intensities. I showed this to an "Ancients" cataloger and he mentioned to me, "It's an attractive portrait".
