France
Charles X 5 Francs 1830-A MS65 NGC, Paris mint, KM728.1. Singularly the finest-known certified example of this date/mintmark, with phenomenal argent surfaces sheathed in a satin finish and the beginnings of amber color clinging to the raised elements. A visual stunner with a desired technical quality to match, conditionally rare as such.
Estimate: 1000-1200 USD
