Claudius II (268-270), Antoninianus, Siscia mint, second officina. Obverse: IMP CLAVDIVS AVG, radiate, draped and cuirassed bust with paludamentum left, seen from the front; Reverse: PA-X A-VG, Pax standing left, holding olive branch in right hand and long transverse sceptre in left hand; II in left field; RIC - , RIC V Online - At first glance it doesn't seem like anything special: it does have nice details, but it lacks eye appeal and it was also struck on a pretty awful flan. However, it has something very special: this bust type, D1l, is known for three different reverse types of the Siscia mint (LAETITIA AVG, SPES AVG and AEQVITAS AVG), but not with PAX AVG, like my coin. I have been unable to find any other coin like this, and it's even missing from RIC V Online. I also haven't found an obverse die match for this coin, though, if anyone wants to take a look, here's the RIC V Online page for the Siscia coins with this bust type: http://www.ric.mom.fr/en/search/adv...ion=&Note=&Reference=&page=1&hpp=5&mod=result Have you ever found a previously unknown variety of a coin?
