Prussia. Wilhelm II gold Proof 20 Mark 1890-A PR62 NGC, Berlin mint, KM521. A sunny golden offering with just a hint of cameo contrast. The devices are bold, set within watery reflective fields and displaying only light handling. Currently the finest graded example at NGC, tied with a single specimen at PCGS, also the finest seen by them.
