Coin

Coin is the basic form of money in the Dishonored franchise. In the Empire of the Isles, characters such as Corvo Attano, Emily Kaldwin, Daud and Billie Lurk can acquire coin by collecting coins, pouches and completing certain quests. They can also collect various valuable items to sell on the black market. These items range in value from copper wire, worth only 10 coin, to Sokolov paintings, worth 300 coin. The Void Walker's Arsenal adds in four pouches worth 500 coin each, while the Imperial Assassin's Pack gives 500 extra coin.

Like runes and bone charms, each mission also tracks how much money the protagonist has managed to acquire out of a set total, with the Sokolov paintings also having their own counter.

Background
Coin represents both the physical and abstract value of any given item or trade throughout the Empire of the Isles. Denominations in circulation typically include copper, silver, and gold. Each isle in the Empire mints their own currency, typically stamping the profile of their rulers on one side, though the coins are standardized enough that they can be traded throughout the Isles without hassle. Coins with the images of Jessamine Kaldwin, Emily Kalwin and even Hiram Burrows can be found in the circulation, and according to The Heart, Luca's image, and coincidentally Armando's, was first placed on the Serkonan currency in 1847. By 1853, coins engraved with Alexy Olaskir's name are still being used in far-flung corners of the Empire.

Trivia

 * Similarly to the game series Thief, each mission in the Dishonored franchise has a set amount of coins and valuables, and so a specific total of coin value available, which is displayed in the stats once the mission is done. Unlike the Thief series however, collecting coins is never a requirement to complete a mission.
 * In Dishonored, Corvo gives the items he collects to Piero Joplin to resell on the black market. It is not revealed exactly how Daud sells the items he procures. In Dishonored 2 and Death of the Outsider, Corvo, Emily and Billie sell their items to the black market shops themselves.
 * The Perth, Inchmouth, Carmine and Archer families are only heard about through their heirlooms. No members of the Brigmore family are met, and members of the other families can be encountered during the game.
 * The Brigmore Urn and Brigmore Whale Statuette are the only heirlooms that can be collected twice.
 * Despite allegedly being of different areas or locations, all maps appear exactly the same in-game.
 * In Dishonored and its DLC, they are world maps, representing both the Empire and the Pandyssian continent.
 * In Dishonored 2, they have the texture of the Empire's new map.
 * A Butcher's buzz-saw is worth 20 coin. As varying numbers of Butchers spawn, the buzz-saws do not count towards the level's coin total.
 * In Dishonored and its DLC, the only currency to be found are coins minted with the Lord Regent's portrait and the motto "Regent Watch Us".
 * In Dishonored 2, three additional currencies can be found:
 * Two using the same designs as the previous one with the portrait of either Empresses Jessamine and Emily Kaldwin and the motto "Empress Protect Us".
 * One with the portrait and name of Duke Luca Abele and the motto "Serkonos For Him".
 * Coins found in the abandoned apartment in A Long Day in Dunwall are minted with the Lord Regent's portrait and are visually the same as the coins found in Dishonored, as the apartment had not been opened up since 1837.
 * In the Dishonored Roleplaying Game, iron coins have the lowest value, copper coins are worth 2, silver coins are worth 5 and gold coins are worth 10.
