That really is a "good for the grade" example of a 38/7 semilibral uncia. Nice find, and historically interesting as well, as it was part of the Crawford 38 series, struck as Rome was transitioning from cast to struck bronze coinage and before the introduction of the denarius. In this series, the quadrans and larger denominations are all cast, and the sextans(2 unciae) and below were all struck. I've got an example of the semuncia from the same series, it was my first RR bronze actually:
My first RR bronze or at least the first one I still have is this 14.17g uncia I bought in 1988. Was the soil around Rome particularly hard on coins or was that region early to adopt chemical fertilizers adding texture to our surfaces?
Sporky! Love your coin, so you made me search under Crawford 38, and I found a few that I have...
