The primary currency in Erekiath, Sylvania and The Snowy Peaks is the Pact. It's a coin, and are made from either copper, silver, gold, or platinum.
There are ten copper pacts on a silver pact, ten silver pacts on a gold pact, and a hundred gold pacts on a platinum pact.
Platinum is rarely seen and is mostly used between the wealthiest of people, to conduct business with expensive or large quantities of goods.
Coins from other countries are generally accepted, as long as the metal and size are roughly the same. Merchants are allowed to refuse payment in foreign coins, whereas a pact can generally not be refused as payment.
