    Countermark likely applied during the reign of Nero (AD 54-68), possibly in Gallia Lugdunensis. The mark stands for PROB(are), which was one of a series of denominational countermarks on Julio-Claudian sestertii, in this case marked approved/certified for value as a sestertius. Other marks include DV and DVP to revalue to a dupondius and AS to revalue to an as.
