RPC: No real picture emerges as to the nature and mint(s) of this coinage. It is not clear if it was colonial or provincial and if it was struck in different mints; its area of diffusion was mainly Macedonia, Troas, Bithynia and Mysia were it probably passed for a semis.

The pomerium or pomoerium (Latin, from post + moerium > murum, "wall"), was the sacred boundary of the city. In legal terms, Rome existed only within the pomerium; everything beyond it was simply land belonging to Rome.
