Great Britain
George IV 1/2 Crown 1820 MS66 PCGS, Royal mint, KM676, S-3807. Extremely rare in this condition; the sole MS66 graded by PCGS, with one finer at MS66+, and none higher than MS65 graded by NGC. As such, the second finest graded example. Gray toning with faint rainbow iridescence peeking through to the surface. A truly premium coin in exceptional condition.
