Prussia. Wilhelm I gold 10 Mark 1888-A MS66 NGC, Berlin mint, KM504, Jaeger-245. The final year of this long-running type with choice, satiny texture over minimally marked surfaces. While considered common as a type, undeniably rare this nice, with the present example being the lone MS66 to be certified by either NGC or PCGS.From The Kaiser Collection of German Gold Coins
