The United States one-cent coin, often called the penny, is a unit of currency equaling one one-hundredth of a United States dollar. It has been the lowest-value physical unit of U.S. currency since the abolition of the half-cent in 1857. The first U.S. cent was produced in 1787, and the cent has been issued primarily as a copper or copper-plated coin throughout its history. Its obverse has featured the profile of President Abraham Lincoln since 1909, the centennial of his birth. From 1959 to 2008, the reverse featured the Lincoln Memorial. Four different reverse designs in 2009 honored Lincoln's 200th birthday and a new, "permanent" reverse – the Union Shield – was introduced in 2010. The coin is 0.75 inches (19.05 mm) in diameter and 0.0598 inches (1.52 mm) in thickness. Its weight has varied, depending upon the composition of metals used in its production.
The dime, in United States usage, is a ten-cent coin, one tenth of a United States dollar, labeled formally as "one dime". The denomination was first authorized by the Coinage Act of 1792. The dime is the smallest in diameter and is the thinnest of all U.S. coins currently minted for circulation, being .705 inch (17.91 mm) in diameter and .053 inch (1.35 mm) in thickness. The obverse of the current dime depicts the profile of President Franklin D. Roosevelt and the reverse boasts an olive branch, a torch, and an oak branch, from left to right respectively. As of 2011, the dime coin cost 5.65 cents to produce.
The United States three cent piece was a unit of currency equaling 3⁄100 of a United States dollar. The mint produced two different three-cent coins for circulation: the three-cent silver and the three-cent nickel. Additionally, a three-cent bronze coin was made as a pattern in 1863. During the period from 1865 to 1873, both coins were minted, albeit in very small quantities for the silver three-cent piece.
The half dime, or half disme, was a silver coin, valued at five cents, formerly minted in the United States.
The American twenty-cent piece is a coin struck from 1875 to 1878, but only for collectors in the final two years. Proposed by Nevada Senator John P. Jones, it proved a failure due to confusion with the quarter, to which it was close in both size and value.
The United States large cent was a coin with a face value of 1/100 of a United States dollar. Its nominal diameter was 11⁄8 inch (28.57 mm). The first official mintage of the large cent was in 1793, and its production continued until 1857, when it was officially replaced by the modern-size one-cent coin.
The coins of Newfoundland are of historical importance as Newfoundland was a British colony until 1907, and a Dominion until 1949, when Newfoundland and Labrador became the tenth province of Canada.
The quarter eagle was a gold coin issued by the United States with a denomination of two hundred and fifty cents, or two dollars and fifty cents. It was given its name in the Coinage Act of 1792, as a derivation from the US ten-dollar eagle coin. Its purchasing power in 1800 would be equivalent to $71.12 in 2015 dollars.
The Shield nickel was the first United States five-cent piece to be made out of copper-nickel, the same alloy of which American nickels are struck today. Designed by James B. Longacre, the coin was issued from 1866 until 1883, when it was replaced by the Liberty Head nickel. The coin takes its name from the motif on its obverse, and was the first five-cent coin referred to as a "nickel"—silver pieces of that denomination had been known as half dimes.
The Australian twenty-cent coin of the Australian decimal currency system was issued with conversion to decimal currency on 14 February 1966, replacing the florin which was worth two shillings – a tenth of a pound.
The Australian five-cent coin is the lowest-denomination circulating coin of the decimal Australian dollar introduced in 14 February 1966, replacing the pre-decimal sixpence. It has been the lowest-denomination coin in general circulation since the withdrawal of the one-cent and two-cent coins in 1992.
The Australian ten-cent coin is a coin of the decimal Australian dollar. When the dollar was introduced as half of an Australian pound on 14 February 1966, the coin inherited the specifications of the pre-decimal shilling; both coins were worth one twentieth of a pound. On introduction it was the fourth-lowest denomination coin. Since the withdrawal from circulation of the one and two cent coins in 1992, it has been the second-lowest denomination coin in circulation.
Canadian coinage is the coinage of Canada, produced by the Royal Canadian Mint and denominated in Canadian dollars ($) and the subunit of dollars, cents (¢). An effigy of the reigning monarch always appears on the obverse of all coins. There are standard images which appear on the reverse, but there are also commemorative and numismatic issues with different images on the reverse.
The American Buffalo, also known as a gold buffalo, is a 24-karat bullion coin first offered for sale by the United States Mint on June 22, 2006, and available for shipment beginning on July 13. The coin follows the design of the Indian Head nickel and has gained its nickname from the American Bison on the reverse side of the design. This was the first time ever that the United States Government has minted pure (.9999) 24-karat gold coins for the public. The coin has a legal tender (face) value of US$50. Due to a combination of the coin's popularity and the tremendous increase in the price of gold since its creation the coin's value has increased considerably in a short time of just a few years. The initial 2006 U.S. Mint price of the proof coin was $800. In 2007 the Mint proof coin was $899.95, $1,410.00 in 2009, and $2,010.00 in 2011.
"Draped Bust" was the name given to a design of United States coins. It appeared on much of the regular-issue copper and silver United States coinage, 1796–1807. It was designed by engraver Robert Scot.
Work on the coinage tools for the Newfoundland five-cent coin began after the one-cent coin, so the coin has no legend. The first pattern is derived from the New Brunswick obverse with Newfoundland substituted for New Brunswick.
The first known pattern for the Newfoundland 20-cent piece is a bronze strike with an obverse derived from a New Brunswick coin. The reverse is from the die for the 1864 New Brunswick 20-cents. The twenty-cent denomination was very popular in Newfoundland and was minted on a consistent basis throughout the reign of Queen Victoria. Over the years the piece became unpopular with Canadians as it was easily confused with the Canadian 25-cent piece, which was similar in size and shape. Pressured by Canada, the government replaced it with a twenty-five cent coin during World War I.
The Newfoundland ten cent coins exist as a bronze pattern with the adopted obverse from the New Brunswick coin. This design adoption is similar to that used for Newfoundland five cent coins.
The Newfoundland 2-dollar coin was issued in intermittent years between 1865 and 1888. It was the only circulation gold coin issued by a British colony. Although few coins were issued, it was broadly used in Newfoundland and eastern Canada. The coin became scarce in 1894 because of hoarding following the collapse of Newfoundland's banks and monetary system.
The New Zealand fifty-cent coin is a coin of the New Zealand dollar. It was the largest by denomination, diameter and mass to have been introduced on the decimalisation of the currency on 10 July 1967, replacing the pre-decimal crown coin.
