Hello,

 

Please add the following regnal era for Roman provincial coins:


Rome - Gallienus era

 

Year 1 corresponds to September AD 253 - August AD 254 so it could be set to 253. It used the Julian calendar.

 

for this coin:

N#376329

 

Thank you

Please also add the following regnal era for Roman provincial coins:


Rome - Diocletian era

 

Year 1 corresponds to 20 November AD 284 - August AD 285. Subsequent years changed in August.

So I suppose year n could be set to 283 + n 

 

for this coin:

Thank you

All these Roman era calendars are used only within Roman Empire and provinces, right?

Roman republic too. And I think the Caesarean, Actian, and Pompeian eras were also used in other places, like some Ptolemaic cities, but not sure.

Ok, thank you!

Thank you. I added both calendars.
