Italy
Sicily. Ferdinando III Oncia of 30 Tari 1791 GL-CI MS61 NGC, Palermo mint, Gabriel Lancilotto Castello as mintmaster, KM221 (prev. KM-C37a), Dav-1420, Spahr-2, MIR-597. Attractively toned, one hardly ever encounters large-size Italian silver coins of this period, especially in such an exceptional state of preservation as this. Worthy of careful consideration, as one does not know the next time they'll be able to acquire an example of this type in Mint State.
