Isabel II Proof 20 Reales 1850 PR64 PCGS, Madrid mint (6-pointed star), KM593.2 (unlisted in Proof), type of Cayon-17187 (unlisted in Proof). Obv. Bust of Isabel II right with date below. Rev. Crowned arms between pillars, with value below. A stunning example of this exceedingly rare Proof issue. The strike is flawless, with mirrored fields, and the superb toning is a visually pleasing gray and russet blend. No mentionable flaws are noted and the overall appearance is spectacular. A gorgeous coin, and the grading of PR64 is very conservative. Only 4 pieces have been certified in Proof by PCGS and NGC, with this example the finest of the four.
