Aquitaine. Edward the Black Prince (1362-1372) Sterling ND VF35 NGC, Dax mint, Second Issue, Elias-189 (RR), W&F-208 8/b (R). 16mm. 1.04gm. Virtually never encountered with such a fine level of detail and painstaking level of engraving--surely indicating the work of a master--softness kept to a bare minimum, and the sharpness of the letters suggesting a somewhat conservative grade.
