Answer:
People would trade for Roman coins even if they did not want Roman goods.
Step-by-step explanation:
Currency allowed the Romans to trade even if they had no trade goods that other people wanted. Roman coins were valuable in themselves because they were made of silver. They were also valuable because the powerful Roman government supported them. People from a non-Roman tribe or nation would trade for coins because, even if they had no need for the silver, they knew other people would trade for the coins later. :)
