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.

Legal tender is a form of money that courts of law are required to recognize as satisfactory payment for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt.

The Tuvaluan dollar is one of the currencies of Tuvalu, whose unofficial international currency code is TVD. Tuvalu has never had banknotes of its own, and has been issuing coins since 1976. However, the Tuvaluan dollar is used as a unit of account, and is pegged to the Australian dollar at parity. From 1966 to 1976, Tuvalu officially used the Australian dollar. In 1976, Tuvalu began issuing its own coins, which continue to circulate alongside Australian coins. Tuvalu continues to use Australian banknotes. Tuvaluan coins are not legal tender in Australia. Similar to the Faroese króna's relationship to the Danish krone and the Panamanian balboa's relationship to the United States dollar, the Tuvaluan dollar is not an independent currency, but a variation of the Australian dollar.
