The United States one-cent coin, often called the penny, is a unit of currency equaling one one-hundredth of a United States dollar. The cent's symbol is ¢. 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 coin 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 half dollar, sometimes referred to as the half for short or 50-cent piece, is a United States coin worth 50 cents, or one half of a dollar. It is the largest United States circulating coin currently produced in both size and weight, being 1.205 inches (30.61 mm) in diameter and .085 inches (2.15 mm) in thickness, and is twice the weight of the quarter. The coin's design has undergone a number of changes throughout its history. The current half dollar, the Kennedy half dollar, depicts the profile of President John F. Kennedy on the obverse and the Seal of the President of the United States on the reverse.
The half dime, or half disme, was a silver coin, valued at five cents, formerly minted in the United States.
The half cent is the smallest denomination of United States coin ever minted. It was first minted in 1793 and last minted in 1857. It was minted with five different designs.
The Seated Liberty portrait designs appeared on most regular-issue silver United States coinage during the mid- and late nineteenth century, from 1836 through 1891. The denominations which featured the Goddess of Liberty in a Seated Liberty design included the half dime, the dime, the quarter, the half dollar, and until 1873 the silver dollar. Another coin that appeared exclusively in the Seated Liberty design was the twenty cent piece. This coin was produced from 1875 to 1878, and was discontinued because it looked very similar to the quarter. Seated Liberty coinage was minted at the main United States Mint in Philadelphia, as well as the branch mints in New Orleans, San Francisco, and Carson City.
The Flowing Hair dollar was the first dollar coin issued by the United States federal government. The coin was minted in 1794 and 1795; its size and weight were based on the Spanish dollar, which was popular in trade throughout the Americas.
The Indian Head cent, also known as an Indian Head penny, was a one-cent coin ($0.01) produced by the United States Bureau of the Mint from 1859 to 1909. It was designed by James Barton Longacre, the Chief Engraver at the Philadelphia Mint.
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 Flying Eagle cent is a one-cent piece struck by the Mint of the United States as a pattern coin in 1856 and for circulation in 1857 and 1858. The coin was designed by Mint Chief Engraver James B. Longacre, with the eagle in flight based on the work of Longacre's predecessor, Christian Gobrecht.
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 silver center cent is an American pattern coin, one of the precursors to the large cent and an early example of a bimetallic coin. Less than a dozen specimens are known to exist today, and they generally fetch substantial prices; an uncirculated silver center cent sold at auction for $414,000 in January 2002. That price was eclipsed by an example graded PCGS MS61 offered at auction in April 2012, with a price tag of more than $1 million.
Canadian coinage is the coinage of Canada, produced by the Royal Canadian Mint and denominated in Canadian dollars ($) 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 Half union was a United States coin minted as a pattern, or a coin not approved for release, with a face value of fifty U.S. Dollars. It is often thought of as one of the most significant and well-known patterns in the history of the U.S. Mint. The basic design, featuring Liberty on the obverse, was slightly modified from the similar $20 "Liberty Head" Double Eagle, which was designed by James B. Longacre and minted from 1849 to 1907.
The Liberty Cap large cent was a type of large cent struck by the United States Mint from 1793 until 1796, when it was replaced by the Draped Bust large cent. The coin features an image of the goddess of Liberty and her accompanying Phrygian cap.
