Great Britain
Edward VII gold Sovereign 1910, S-3969, KM805, MS64 PCGS, a beauty with satiny luster and a sharp strike. Common in XF and AU as one of the "kings sovereigns" but difficult to find with mint frost and such choice surfaces. Only a handful of sovereigns of this king have been graded above MS63 by each TPG company.
Estimate: 400-600 USD
