Coin is used in most human and dwarven societies. Cultures that have little value for coins, such as the Dalish, commonly exchange goods in contrast. 
The standard currency was developed by the Dwarven Merchants' Guild, making the Dwarves the first race to create the coinage.  which refused to accept any other currency that did not meet their specifications. This forced most nations to quickly convert. Particularly expensive transactions may be completed in "bars" (solid bricks) and "strands" (stacked groups), but those are the province of merchant guilds and governments, and thus rarely seen in regular commerce. 
List of Coins
Sovereigns/Silvers/Bits: The gold/silver/bronze coins of Ferelden, respectively.
Royals/Crowns/Pennies: The gold/silver/bronze coins of Orlais, respectively.
King's Gulder: The gold coins of Nevarra. 
Double Griffon - The gold coins of the Anderfels. 
Andris: The currency of Antiva. The coins feature images of famous guild leaders as opposed to rulers. An amount of five thousand andris has come to be known as "one bastard," which is occasionally used as veild insult in negotiations. One andris is equivalent to one royal. 
Andraste's Tear: Created an experiment to see if a nonmetalic coin would catch on for collectors' purposes, Andraste's Tear was made of glass, influenced by the makers of Serault Glassworks. One coin is worth five royals. 
Caprice: Caprice coins adorn a family heraldry or designs based on a singular event. Used as part of grand parties in Orlais, the coins are intended to be disposable and have a "small" weight in gold. Orlesian nobility exchange the coins as a reward for dashing remarks and grace. 
Imperial Tesserae: In the Tevinter Imperium, tesserae coins are used to allow entry to certain events. Collectors favour those created for combat. The more intimate the event, such as a private mistral performance, the higher the value. After the even has passed however, they mean little more than a souvenir. 
- Zevran claims he'd charge five thousand andris for killing Alistiar. This is of course, poking at the fact that he's Maric's bastard son.
- "The Traveller's Bend" was a practice used on what would become the Imperial Highway. As a means of thwarting bandits, gold coins would be beaten into a curved shape to fit under the tongue or upon the palate. It was not unknown for someone to choke on their own cashe. The trend died out when it was linked to the illness known as "misner's madness," caused by hiding lesser Hunter Fell currency struck from lead.
