Significance

The earliest copper coins of the denomination 'as' weighed one Roman pound (about 329 g.) and were produced by casting from about 280 BC. There were 12 Roman uncia in a Roman pound and 12 uncia coins to the as. This coin, an uncia, has the one dot for the denomination on each side. As with all Roman copper coins of that period, the weight of the coin denominations were gradually reduced. Uncia coins with the weight of this example were being produced between 225 BC and 217 BC. Cast coins were not produced with exact weights but the average weight of a large sample would have been close to the desired standard.
