Coin can be found and acquired through a large number of ways, some depending on the civilization that a player chooses.
Coin can be mined from four different types of deposits. These are Tin Mines, Copper Mines, Silver Mines, and Gold Mines. Tin Mines hold 1,500 coin, Silver and Copper Mines each hold 2,000 coin, and Gold Mines hold 5,000 coin. To mine coin, all a player has to do is task a Villager (or any other resource gathering unit) on the mine and the unit will automatically mine from it. Gathering rates can be improved with Market upgrades and Home City shipments.
Additional mines can be acquired under special conditions. Unique to the United States, Coal Mines worth 2,000 coin can be constructed by Coal Prospector Wagons. Trading with a Berber settlement allows the training of Berber Salt Camels that spawn Salt Mines worth 10,000 coin. The South Africa Revolution can provide a Diamond Prospector Wagon that spawns a Diamond Mine worth a whopping 100,000 coin.
Players can fund their military efforts by assigning fishing ships to gather coin from various animals of the sea such as Humpback Whales, Beluga Whales, and Minke Whales. Each spot can supply an infinite amount of coin, but only up to four fishing ships may gather from a single spot at a time. Whaling is slower than mining gold, copper, and silver but is recommended for a late game supply of gold when mines are depleted. Gather rates can be improved from Home City shipments and via Dock upgrades. This includes cost reduction cards for fishing ships, or docks as the player can get more of them out quickly. All forms of canoes and the Marathan Catamaran gather much slower than all other fishing ships.
The following buildings can produce coin, or give access to upgrades otherwise unobtainable by a civilization.
All civilizations are able to produce coin through either Rice Paddies (Asian civilizations) or Estates (European civilizations and Native Americans). These buildings have upgrades which make for faster gather rates and there are also cards that can be sent from the Home City to improve the gather rates.
Banks are buildings that are unique to the Dutch civilization. There is a limit of the number of banks that the Dutch can build. Home City Cards allow for cheaper Banks, and a higher Bank build limit. The Japanese are also able to build a single Bank. To do this, the player must ally with the Dutch through the Consulate and pay 400 export to receive a Bank Wagon that can be turned into a Bank. However, this Bank will not be able to be upgraded and no more can be built.
The Church can provide a one time coin shipment for the Knights of St. John, increase bank build limit for the Dutch, or increase gather rate bonus for the French Coureur des Bois if their respective unique building upgrade cards are sent.
Factories can be built by all European civilizations as well as some other civilizations, such as the Chinese and Indians (campaign only). European civilizations can build up to two Factories that can be improved with researchable technologies at the Factory. For the Chinese or the Indians to receive a Factory, the player must ally with the Russians at the Consulate. India cannot ally with Russia outside of the campaign, however. For 800 export, the player can send a Factory to their Home City shipment point.
The Capitol building does not produce coin, however this building (for European civilizations, Town Center for expansion civilizations) can be used to research Excessive Taxation, which will increase gather rates for coin production and provide a +2 limit to Banks for the Dutch.
Shrines can be built by the Japanese and can be configured to automatically produce coin. The generation rates can be increased through the Heavenly Kami card, and building the Toshogu Shrine. Tasking huntable, or Herdable animals on a Shrine will increase production as well.
Consulates produce a trickle of 0.8/sec, or 48/min if the Japanese ally with the Dutch. The Japanese can also temporarily ally with the Spanish to purchase the Nanban Trade upgrade, retaining it even if they later switch to a different ally. Selecting the Germans as an ally for the Chinese at the Consulate will grant an upgrade identical to the below mentioned Capitalism (other methods, trickles), but in the Industrial Age. The fact it can be acquired and the ally changed while still retaining the trickle makes it useful to supplement other late game sources.
Wonders such as the Toshogu Shrine and the Porcelain Tower will also trickle in resources. The Toshugu Shrine will boost the rates of other Shrines as well as act as a powerful shrine itself (but not benefit from the bonus to regular shrines it provides), and the Porcelain Tower can generate all resources simultaneously but at a reduced rate. Both can be configured to generate coin exclusively. The Karni Mata will not trickle in coin, but does boost gather rates of those around it by 10%.
Building Trading Posts at Quechua (mines only), Huron (fishing boats only), Klamath (all unit gatherer types), Navajo (all unit gatherer types, livestock resource generation), Sufi (all unit gatherer types), and Udasi (Estates only) settlements enables coin gather rate improvements. Building one at a Mapuche settlement results in a gain of 100 coin for every two minutes the game has lasted, up to thirty minutes (1500 coin) in the Fortress Age. The Incas and Mapuche share the Araucania map, while the Sufi and Udasi share the Deccan and Silk Road maps.
Markets are another way to acquire coin. Players can sell wood or food in exchange for coin. The Advanced Market card can be sent from the Home City to improve the exchange rates between resources. It is possible to focus on food to sell, and make a profit when using the card, though it is not optimal.
The player can also get coin from finding Treasures. Treasures can award units, experience, unit bonuses, food, wood, and coin. With certain home city shipments this can be done rapidly, or to significantly improved effect (e.g. the Mountain Warrior card as Japan doubles resources gained from treasure hunting).
The player can get coin from friendly players. Demands can be sent to computer players for instant payments of coin or for many amounts over time. In multiplayer, players can also ask teammates for some spare coin if they have run out.
- Politicians and the tribal council
- Exchange cards
The French, Haudenosaunee, Indians and Chinese possess cards that exchange all of their current food, or export for a greater amount of coin. The exchange rates are 1.25 coin for 1 food (Fur Trade), and 1.6 coin for 1 export (Dowager Express).
The Home City Card Capitalism, available to the Spanish, Germans, and Ottomans in the Exploration Age, grants a permanent trickle of 1.25 coin per second, or 75 a minute. This is equivalent to 2.1 Settlers (1.82 Dutch settlers) or Villagers, 1.7 Coureur des Bois, or Cree Coureur des Bois, or 1.1 Settler Wagons gathering from a mine without any gather rate bonuses. One of the better uses of the card is as the second shipment for the Spanish (whose civilization bonus usually means three shipments in the Exploration Age), with Advanced Trading Posts as the first so as to gain a gold trickle that cannot be lost comparable to owning a trading post delivering coin without the upgrade required, while the actual owned trading posts compound the experience shipment advantage until they can be upgraded to provide even more coin.
The British TEAM Wool Staple Ports card will increase the trickle benefit of herdables tasked to Japanese shrines (including Toshogu), and the experience trickle of Indian herdables, regardless of being tasked to a sacred field or not, by 20%. This grants extra coin (via trickle or quicker shipments).
The Sumptuary Laws (Chinese, Japanese Home City Card in the Exploration Age grants a trickle of 0.3 coin, wood, food, and 0.15 export and experience. The TEAM Sumptuary Laws (Indians) card in the Exploration Age grants a trickle of 0.2 coin, food, wood, and 0.1 export and experience per second to everyone on the team. The single version and team versions stack.
Age of Empires III also offers the option of Home City shipments as a means to get extra coin. Once selected, coin arrives in the form of chests to the shipment point which by default is Town Center. Villagers must work on them to unpack them to the coin supply.
- The Tax Burden upgrade available to the Knights of St. John is only available if the player sends the Royal Decree to Claim the New World card. It provides 100 coin for every minute the game has lasted, up to 30 minutes (3000 coin). If sent after at least 23 minutes, it is the most gold one can receive in a single shipment.
- The Mapuche Treaty of Quillin is only available with the The WarChiefs expansion, and they are the only minor civilization to offer any type of coin crate shipment outside of the campaigns.
- Every civilization can ship the 300 Coin card infinitely in the Exploration Age.
- Every civilization may ship the 600 Coin card and 700 Coin card in the Colonial Age.
- The Ottomans also ship and share with allied players TEAM 600 Coin card in the Industrial Age.
- Every civilization except the Spanish may ship the 1000 Coin card in the Fortress Age.
- The Ottomans may also ship and share with allied players the TEAM 1000 Coin card in the Industrial Age.

- The Ottomans may ship and share "TEAM Silk Road" card which will increase all the coin, food, and wood shipping containers above from 100 to 115 among allied players as well.
- Every shipment card can be unlocked among the New World Trading cards in the consequent order as listed below, except for the Ottomans.
- The Ottomans' 700 Coin and TEAM 600 Coin cards both require the 600 coin card to be unlocked.
- The 1,000 Coin card needs the 700 Coin card to be unlocked.
- "TEAM Silk Road" requires the 1000 Coin card to be unlocked.
- "TEAM 1000 Coin" needs the "TEAM 700 Coin" card to be unlocked.
- The Japanese require a Consulate, and 550 export total to purchase the Nanban Trade upgrade.
- Treasure Ships
Treasure Ships are available in some campaign scenarios, and need to be captured to produce coin. This is accomplished by destroying an outpost, and guarding force. The ships cannot be damaged or recaptured by the enemy.
Coin can also be obtained by entering the cheat code give me liberty or give me coin. Doing so instantly grants + 10,000 coin.
