Adorning its obverse is the profile of George Washington, while its reverse design has undergone frequent changes since 1998. Since its initial production in 1796, the quarter dollar has held a significant place in American numismatics, with consistent production since 1831.
Pietas, translated variously as "duty", "religiosity" or "religious behavior", "loyalty", "devotion", or "filial piety", was one of the chief virtues among the ancient Romans. It was the distinguishing virtue of the founding hero Aeneas, who is often given the adjectival epithet pius ("religious") throughout Virgil's epic Aeneid. The sacred nature of pietas was embodied by the divine personification Pietas, a goddess often pictured on Roman coins. The Greek equivalent is eusebeia (εὐσέβεια).

The krone is the official currency of Denmark, Greenland, and the Faroe Islands, introduced on 1 January 1875. Both the ISO code "DKK" and currency sign "kr." are in common use; the former precedes the value, the latter in some contexts follows it. The currency is sometimes referred to as the Danish crown in English, since krone literally means crown. Krone coins have been minted in Denmark since the 17th century.
Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum and copper coinage. From its introduction during the Republic, in the third century BC, through Imperial times, Roman currency saw many changes in form, denomination, and composition. A feature was the inflationary debasement and replacement of coins over the centuries. Notable examples of this followed the reforms of Diocletian. This trend continued with Byzantine currency.
The obverse and reverse are the two flat faces of coins and some other two-sided objects, including paper money, flags, seals, medals, drawings, old master prints and other works of art, and printed fabrics. In this usage, obverse means the front face of the object and reverse means the back face. The obverse of a coin is commonly called heads, because it often depicts the head of a prominent person, and the reverse tails.
The pfennig ; symbol pf or ₰) or penny is a former German coin or note, which was an official currency from the 9th century until the introduction of the euro in 2002. While a valuable coin during the Middle Ages, it lost its value through the years and was the minor coin of the Mark currencies in the German Reich, West Germany and East Germany, and the reunified Germany until the introduction of the euro. Pfennig was also the name of the subunit of the Danzig mark (1922–1923) and the Danzig gulden (1923–1939) in the Free City of Danzig.

Coins with the same value were issued from other cities in Central Italy, using a cast process.
Roman Republican currency is the coinage struck by the various magistrates of the Roman Republic, to be used as legal tender. In modern times, the abbreviation RRC, "Roman Republican Coinage" originally the name of a reference work on the topic by Michael H.

The German mark was the currency of the German Empire, which spanned from 1871 to 1918. The mark was paired with the minor unit of the pfennig (₰); 100 pfennigs were equivalent to 1 mark. The mark was on the gold standard from 1871 to 1914, but like most nations during World War I, the German Empire removed the gold backing in August 1914, and gold coins ceased to circulate.

The Jefferson nickel has been the five-cent coin struck by the United States Mint since 1938, when it replaced the Buffalo nickel. From 1938 until 2004, the copper-nickel coin's obverse featured a profile depiction of Founding Father and third U.S. President Thomas Jefferson by artist Felix Schlag; the obverse design used in 2005 was also in profile, though by Joe Fitzgerald. Since 2006 Jefferson's portrayal, newly designed by Jamie Franki, faces forward. The coin's reverse is still the Schlag original, although in 2004 and 2005 the piece bore commemorative designs.
The triumvir monetalis was a moneyer during the Roman Republic and the Empire, who oversaw the minting of coins.

Coinage under British governance of the Indian subcontinent can be divided into two periods: East India Company (EIC) issues, pre-1835; and Imperial issues struck under direct authority of the crown. The EIC issues can be further subdivided into two subcategories: the Presidency issues, which comprise separate Madras Presidency, Bombay Presidency, and Bengal Presidency issues; and uniform coinage for all British territories from 1835 to 1858. Imperial issues bear obverse portraits of Queen Victoria, Edward VII, George V, and George VI. No British India coins were issued during the brief reign of Edward VIII.
