Currency of Theros

The nation of Theros and its various city states uses a form of gold coin called a Drakma, it's small and light weight a single belt pouch can hold upwards of 200-300 Drakma without being overly heavy, meant to be carried for long distance so travelers and merchants could make purchases of equivalent value to what they were buying, a single goat or sheep is equivalent of 8 Drakma or one Falcata. The Drakma of Theros would not be recognized in any other nation on Caen, as it is still a fairly new coin, however the gold value of the metal itself could be traded in at a money changer for currency of the realm in which travelers found themselves in.
