Coins of the United States dollar - aside from those of the earlier Continental currency - were first minted in 1792. New coins have been produced annually and they comprise a significant aspect of the United States currency system. Circulating coins exist in denominations of 1¢, 5¢, 10¢, 25¢, 50¢, and $1.00. Also minted are bullion, including gold, silver and platinum, and commemorative coins. All of these are produced by the United States Mint. The coins are then sold to Federal Reserve Banks which in turn put coins into circulation and withdraw them as demanded by the United States economy.

The Napoléon is the colloquial term for a former French gold coin. The coins were minted in denominations of 5, 10, 20, 40, 50, and 100 francs.

Assay offices are institutions set up to assay precious metals. This is often done to protect consumers from buying fake items. Upon successful completion of an assay the assay offices typically stamp a hallmark on the item to certify its metallurgical content. Hallmarking first appeared in France, with the Goldsmiths' Statute of 1260 promulgated under Étienne Boileau, Provost of Paris, for King Louis IX.
The fineness of a precious metal object represents the weight of fine metal therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass.

Canada has an extensive history with regard to its currencies. Prior to European contact, indigenous peoples in Canada used items such as wampum and furs for trading purposes, which continued when trade with Europeans began. During the period of French colonization, coins were introduced, as well as one of the first examples of paper currency by a western government. During the period of British colonization, additional coinage was introduced, as well as banknotes. The Canadian colonies gradually moved away from the British pound and adopted currencies linked to the United States dollar. With Confederation in 1867, the Canadian dollar was established. By the mid-20th century, the Bank of Canada was the sole issuer of paper currency, and banks ceased to issue banknotes.
