Coins of Aeritain

Farthings are small copper coins, the currency of the street and stall. Ten make a Sterling, and most folk trade in farthings daily; for bread, nails, or a bowl of stew. A few farthings will fill your belly; a dozen might rent a bed for the night.
Sterlings are silver coins, the true measure of worth in Aeritain and its colonies, such as Ashkrim. A day’s honest labor earns one. Ten farthings make a sterling, and ten sterlings make a Crown. Prices, wages, debts, all are reckoned in sterling.
Crowns are gold coins, traded by common hands. Worth ten sterlings, or a hundred farthings. Crowns are the domain of nobles, merchants, and those who live dangerously or well. Few poor folk see one; fewer still hold on to it.
