Great Britain
George V gold Sovereign 1913 MS66 NGC, Royal mint, KM820, S-3996. Elite not only for the date, but for the type, with razor-sharp definition throughout and smooth, satiny surfaces that have escaped all but the most trivial forms of handling. Currently, the sole MS66 certified for the date by NGC with none finer, and as such, deserving of significant registry-set collector attention.
