These “City Commemorative” coins seem to be quite popular. Though they are not rare this example is among the nicest I have seen. Somehow I feel like I can’t call myself a Roman Coin Collector without a Romulus and Remus She-Wolf in my collection. Here is the description from Roma: City Commemorative Æ 17mm. Struck under Constantine I. Siscia, AD 334-335. VRBS ROMA, helmeted bust of Roma to left, wearing imperial mantle / She-wolf standing to left, suckling Romulus and Remus, two stars above; •BSIS• in exergue. RIC VII 240 corr. (two stars above). 2.40g, 17mm, 7h.
