The universal currency, money. One has to go very, very far into the boonies to find places that won't recognize the intrinsic value of a golden coin, silver denarius, or copper penny. Physical currency like has two distinct origins: Midasgard, and Nostrum. In Midasgard, they developed a decimalized system of currency where the lowest denominator was an 'as,' and in Nostrum they use a base-12 system where the lowest denominator is a pence.

In the modern day, since the fall of the Empyreans, the Nostrum coinage system is the one recognized throughout the world. Old Empyrean coins are now valued as collector's items, with some people willing to pay a premium for coins minted so long ago.

Part of what makes Nostrum coinage useful across the world is how standardized their size and weight are. A pound coin (literally one pound of silver) is rarely used except as an accounting term. However, a pound of silver is what is given to the royal mints, and some combination of the lesser coinage is thus made, whether that be 240 silver pennies or some other combination.
