<p>[QUOTE="rrdenarius, post: 3373648, member: 75525"]Rome based their monetary system on the As, or Roman pound. The As was divided into twelfths called VNCIA. Note Latin did not have the letter U. Today we call this an ounce. There are many items today that were traded in Roman times as one As. Early cast bronze coins were based on an As and parts expressed in 1/12's. Rome and central Italy did not adhere to the weight standard well. Weights varied by mint and dropped with time.
