The Romans exported substances such as glass, gold, olive oil, meat, beer, marble, salt, silver, wine, tin, wool and copper. The majority of these valuables were transported by boat and were traded with countries known today as Britain, Spain, the Middle East, France, North Africa and the Far East (China).
The Romans also introduced a new type of currency to the counties that they controlled. The idea was that by introducing a universal currency among these countries, the trade would then become simplified. Throughout time, the currency would change. There were 2 different of coins, each from a different time. The first coin was the Aureus. This was introduced from around the 1st century BC to the fourth century
