Italy
Papal States. Sede Vacante Piastra 1655 XF - Mount Removed, Rome mint, Camerlengo Antonio Barberini, KM280, Dav-4069, B-1887. A well-detailed example with just hints of peripheral tone. The mount removal is a hole on the rim and therefore has not left any damage on the faces of the coin.
Estimate: 400-600 USD
