Nomisma was the ancient Greek word for money or coin.

In the Byzantine empire, it the denomination of gold coin. In the late tenth century the nomisma, was split into two separate denominations, a heavier histamenon and a lighter tetarteron. From 1092 onward, the heavier coin was called a hyperpyron, while the lighter coin ceased to be struck. Source: Grierson, Philip. Byzantine Coins. (London, 1999).
