: : I would not have any copper coinage - copper not being intrisically valuable, it is only really found in very sophisticated societies where an arbitrary equivalent value to silver is universally accepted. In the same way that a hundred dollar bill is actually a worthless scrap of paper if the system which gives it a specious value is ignored. In silver-based coinage systems the coins were actually cut into halves, quarters or eighths to give "Small-change."

: : It would be good to give the coin denominations names in keeping with ME. Hobbits could have a Silver Argeleb - after on of the later Arnorian kings, as they would probably have used the last official Arnorian coinage as a model for their later coin issues.
: : Gondorian coins could be Crowns, Stars, etc. - just a thought.
: The early roman system was based on either bronze or copper, do not remember which, never had much interest for money.

The Romans had a coinage using gold, silver and bronze. In the Empire they had a lot of trouble with inflation affecting the value of their base-metal coinage, and for many years their silver coins had the silver content reduced which compounded the inflation. Reforms under Diocletian, Constantine The Great and Anastasius led to the very stable Byzantine currency based on the high purity gold "Nomismata" or "Besant" which was the most respected currency in Europe and the Middle East for many centuries.
