NETHERLANDS. 2-1/2 Gulden, 1938. Utrecht Mint. Wilhelmina I. PCGS PROOF-63. KM-165. A <strong>EXTREMELY</strong> <strong>RARE</strong> coin when presented in proof finish, this choice example displays a mirrorlike reflectivity across the fields with somewhat frosty devices in a blinding aroura of luster. Some friction is evident in the fields, and is likely the reason for the grade on this well-struck piece.
