Ferdinand VII 1/2 Real 1817 So-FI AU Details (Environmental Damage) NGC, Santiago mint, KM64 (this mintmaster unlisted), Calbeto-unlisted, Cayon-unlisted. The "FI" mintmaster is extremely rare and this is the one of only two examples certified by either NGC or PCGS. Despite the "Details" grade this coin has a full strike with superb details and very slight "environmental damage".
Estimate: 1000-1200 USD
