Franz Joseph I gold Proof 100 Korona 1907-KB PR64 NGC, Kremnitz mint, KM490, Fr-256. Tied with four others at the PR64 level between NGC and PCGS, with just one finer. An always popular type, with a matte-proof central motif and regular proof finish outer circle containing the legends. This type of coin finish is very prone to showing handling marks, and so it is quite hard to find a piece in this sort of Choice Mint State condition. An always eagerly contested piece by world gold type collectors.
