Did Romans have coins?
The Romans started using coins quite late, in the 3rd century BC, even though the Greek cities of southern Italy had been circulating coins for quite a long time and the Romans were aware of them. The first currency in Italy was the aes grave (heavy bronze), coins of heavy cast bronze, which begun to be used in central Italy in the 4th century BC in central Italy. It seems that their issue in Rome started in the second half of this century. These coins and the bars which preceded them (see below) were made of bronze, which is a metal which was easily found in Italy. It was not until the Punic wars, when they started trading beyond Italy that the Romans adopted Greek practices in coinage and introduced coins made of silver, which had to be imported into Italy. Silver then became the bullion coin. Bronze and brass was also introduced for coins of lower value. The coins of the Roman Republic were the denarius (silver), sthe estertius (silver), the dupondius (Brass), the as ( bronze) the triens (bronze) the quadrans (bronze) the quincunx (bronze) and the uncia (bronze). Emperor Augustus reformed the monetary system in 27 BC. He introduced gold coins. The coins under his system were the aureus (gold) the quinarius (gold) the aureus the denarius (silver) the quinarius (gold) the argenteus (silver) the sestertius (sliver) the dupondius (brass) the as (brass) the semis (bronze) and the quadrans (bronze). Emperor Diocletian reformed the monetary system in 301 AD. He introduced copper coins. The coins under his system were the solidus (gold) the Argenteus (silver) the nummus (copper) the radiate (20 parts bronze and 1 part silver) the laureate and the denarius (silver). The coins in the late Empire were the solidus, the miliarense (silver) the siliqua (silver) the follis (bronze) and the nummus (copper). Prior to the introduction of coins, the Romans used the aes signatum (stamped bronze) which were cast bars of bronze which were in use in central Italy. It is thought that their use started in the 5th century BC. The earliest of these bars were cast in Etruria, Umbra and Emilia (in northern Italy) and did not have a set weight standard. Their weight varied from 600 grams to 2.5 kilos (1 pound 5 oz. to 5 pounds 8 oz.). They did not have a face value and were used to barter goods by the weight of the bars. The Romans introduced a standard weight for official state issues. These were assigned a given face value. They measured 16 x 9 centimetres (6.3 x 3.5 inches) and weighed 1.5 to 1.6 kilos (3 pounds 5 oz. to 1 pound 8 oz.). There were also smaller bars with lower values. There were also bars which were not state issue and could be made by anyone who had a foundry and were still used to barter by their weight.

Which describes the difference between the copper alloys bronze and brass?
Brass= 60%copper + 40%zinc. Bronze = 80%copper+20%Tin. The words "brass" and "bronze" are often used interchangeably, but they are very different metals. Both are alloys and both contain a lot of copper - but that is where the similarities end. Comparatively, brass is a very soft metal. For example, it is used for plumbing fixtures because it is easy to work with and easily tooled. Brass is not as hard as bronze. Brass is also prone to corrosion, so most plumbing fixtures are coated with another metal such as chrome to make it more durable. You will find that a brass bell does not sound as pure as a bronze bell. Brass bells have kind of a "clangy" or "brassy" sound to them. Bronze on the other hand is very hard and can last forever. In fact, there are several grades of bronze. A type called admiralty bronze was used for cannons and is used for propellers on boats.
