NERO CLAVDIVS DRVSVS GERMAN IMP
Host coin RSC I 98; Countermark Pangerl 60
Good Fine. Brown patina with brighter high points. A scarce type with a clear countermark. Large corrosion spot on reverse. Scattered marks.
This countermark is now believed to have been applied during the reign of Vespasian and likely abbreviates 'Nummus Caesare Augusto Probatus,' meaning that the coin had been approved by the Emperor following the Civil War of 69 A.D. It has also been interpreted as abbreviating 'Nero Caesar Augustus Populo Romano,' perhaps applied during Nero's congiarium, or distribution, to the people.
