Livorno. Cosimo III de' Medici gold Ongaro 1674 AU55 PCGS, Florence mint, Fr-464, MIR-72 (R3). A charming and very rare coin, minted with an obverse style of Hungarian Ducats of the period and therefore leading to the nickname of Ongaro. The devices are sharply struck with a small area of weakness in the reverse legend and the lustrous surfaces display little circulation wear.
