Десятицентовый доллар США: история и особенности

Current denomination of United States currency

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 in diameter and 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. The word dime comes from the Old French disme (Modern French dîme), meaning "tithe" or "tenth part", from the Latin decima [pars]. The dime is currently the only United States coin in general circulation that is not denominated in terms of dollars or cents. as of 2011, the dime cost 5.65 cents to produce.

The Coinage Act of 1792 established the dime (spelled "disme" in the legislation), cent, and mill as subdivisions of the dollar equal to 1/10, 1/100 and 1/1000 dollar respectively. The first known proposal for a decimal based coinage system in the United States was made in 1783 by Thomas Jefferson, Benjamin Franklin, Alexander Hamilton, and David Rittenhouse. Hamilton, the nation's first Secretary of the Treasury, recommended the issuance of six such coins in 1791, in a report to Congress. Among the six was a silver coin, "which shall be, in weight and value, one tenth part of a silver unit or dollar". From 1796 to 1837, dimes were composed of 89.24% silver and 10.76% copper, Thus dimes are made small and thin. The silver percentage was increased to 90.0% with the introduction of the Seated Liberty dime; the use of a richer alloy was offset by reducing the diameter from 18.8 millimeters (0.740 inches) to its current figure of 17.9 millimeters (0.705 inches). With the passage of the Coinage Act of 1965, the dime's silver content was removed. Dimes from 1965 to the present are struck from a clad metal composed of outer layers of 75% copper and 25% nickel alloy, bonded to a pure copper core. Pre 1965 dimes followed Gresham's law and vanished from ordinary currency circulation at face value. Most now trade as informal bullion coins known as junk silver, priced at some multiple of face value, which price follows the spot price of silver on commodity markets. Starting in 1992, the U. S. Mint began issuing Silver Proof Sets annually, which contain dimes composed of the pre 1965 standard of 90% silver and 10% copper, then switched to .999 fine silver from 2019 onward. These sets are intended solely for collectors and are not meant for general circulation.

The first dime to be circulated was the Draped Bust dime, in 1796. It featured the same obverse and reverse as all other circulating coins of the time, the so called Draped Bust/Small Eagle design. This design was the work of then Chief Engraver Robert Scot. The portrait of Liberty on the obverse was based on a Gilbert Stuart drawing of prominent Philadelphia socialite Ann Willing Bingham, wife of noted American statesman William Bingham. The reverse design is of a small bald eagle surrounded by palm and olive branches, and perched on a cloud. Since the Coinage Act of 1792 required only that the cent and half cent display their denomination, Draped Bust dimes were minted with no indication of their value. All 1796 dimes have 15 stars on the obverse, representing the number of U. S. states then in the Union. The first 1797 dimes were minted with 16 stars, reflecting Tennessee's admission as the 16th state. Realizing that the practice of adding one star per state could quickly clutter the coin's design, U. S. Mint Director Elias Boudinot ordered a design alteration, to feature just 13 stars (for the original Thirteen Colonies). Therefore, 1797 dimes can be found with either 13 or 16 stars.

The Draped Bust design was succeeded by the Capped Bust, designed by Mint Assistant Engraver John Reich. Both the obverse and reverse were changed extensively. The new reverse featured a bald eagle grasping three arrows (symbolizing strength) and an olive branch (symbolizing peace). Covering the eagle's breast is a U. S. shield with six horizontal lines and 13 vertical stripes. Also on the reverse is the lettering "10C," making it the only dime minted with the value given in cents (subsequent issues are inscribed with the words "ONE DIME"). The lack of numeric value markings on subsequent dime coins causes some confusion amongst foreign visitors, who may be unaware of the value of the coin. Also, the Capped Bust dime was the first dime to have its value written on the coin. Previous designs of the dime had no indication of its value, the way people determined its value was by its size

Capped Bust dimes minted through 1828 are known as the Large type. This is partially because they were struck without a restraining collar, which gave them a broader appearance. In 1828, Chief Engraver William Kneass introduced the close collar method of coining (which automated the process of placing reeds on a coin's edge). In addition to standardizing the diameter of coins, the new method allowed the Mint to produce thicker coins. To maintain a standard weight and alloy, the diameter of most coins was reduced. In particular, the dime was reduced in diameter from 18.8 to 18.5 millimeters. This new Capped Bust dime, which began production in 1828, is known as the Small type. There are 123 varieties known of Capped Bust Dimes.

Christian Gobrecht completed the design of the Seated Liberty dime, whose obverse was used with every circulating silver U. S. coin of the period. Mint Director Robert Maskell Patterson requested a new coin design, to be reminiscent of the Britannia image found on coinage of the United Kingdom. Chief Engraver William Kneass drew the original sketches, but suffered a stroke and was too ill to finish them or to oversee preparation of the dies. The task then fell to Gobrecht, who was promoted to Second Engraver. The obverse features an image of Liberty sitting on a rock, wearing a dress and holding a staff with a liberty cap on top. Her right hand is balancing a shield with the inscription "LIBERTY." The reverse featured the inscription "ONE DIME," surrounded by a wreath. All Seated Liberty dimes contain 90% silver and 10% copper, and are 17.9 millimeters (0.705 inch) in diameter. This size and metal composition would continue until 1965, when silver was permanently removed from circulating dimes. These were replaced with the legend "United States of America," which was moved from the reverse in mid 1860. At the same time, the laurel wreath on the reverse was changed to a wreath of corn, wheat, maple, and oak leaves and expanded nearly to the rim of the coin. This reverse design continued through the end of the series in 1891 and was changed only slightly in 1892, when the Barber dime debuted. Another variety is the 1838–40 dime minted with no drapery underneath the left elbow of Liberty. The change also ensured the quarter dollar (which is valued 2.5 times the dime) weighed 2.5 times the dime (6.25g), and the half dollar (twice the value of the quarter dollar) weighed twice what the quarter dollar weighed (12.5g). In this way, a specific weight of these coins, no matter the mixture of denominations, would always be worth the same. This relation in weight and value continued in the cupronickel coins from 1965 on. This produced the greatest rarities in the Seated Dime Series, the 1873 and 1874 Carson City Dimes, with arrows and the unique 1873 Carson City Dime without arrows.

The Barber dime is named for its designer, Charles E. Barber, who was Chief Engraver of the U. S. Mint from 1879 to 1917. The design was shared with the quarter and half dollar of the same period. Extensive internal politics surrounded the awarding of the design job, which had initially been opened to the public. A four member committee (which included Barber), appointed by then Mint Director James Kimball, accorded only two of more than 300 submissions an honorable mention. Kimball's successor, Edward O. Leech, decided to dispense with the committees and public design competitions and simply instructed Barber to develop a new design. It has been speculated that this is what Barber had wanted all along. The Barber dime, as with all previous dimes, featured an image of Liberty on the obverse. She is wearing a Phrygian cap, a laurel wreath with a ribbon, and a headband with the inscription "LIBERTY". This inscription is one of the key elements used in determining the condition of Barber dimes. The composition (90% silver, 10% copper) and diameter (17.9 millimeters) of the "Mercury" dime was unchanged from the Barber dime. Weinman (who had studied under Augustus Saint Gaudens) won a 1915 competition against two other artists for the design job, and is thought to have modeled his version of Liberty on Elsie Kachel Stevens, wife of noted poet Wallace Stevens. The dime was chosen to honor Roosevelt partly due to his efforts in the founding of the National Foundation for Infantile Paralysis (later renamed the March of Dimes), which originally raised money for polio research and to aid victims of the disease and their families. Due to the limited amount of time available to design the new coin, the Roosevelt dime was the first regular issue U. S. coin designed by a Mint employee in more than 40 years. Chief Engraver John R. Sinnock was chosen, as he had already designed a Mint presidential medal of Roosevelt. Sinnock's design placed his initials ("JS") at the base of Roosevelt's neck, on the coin's obverse. His reverse design elements of a torch, olive branch, and oak branch symbolized, respectively, liberty, peace, and strength. The Mint quickly issued a statement denying this, confirming that the initials were indeed Sinnock's. The same rumor arose after the release of the Sinnock designed Franklin half dollar in 1948. Another controversy surrounding Sinnock's design involves his image of Roosevelt. Soon after the coin's release, it was claimed that Sinnock borrowed his design of Roosevelt from a bas relief created by African American sculptor Selma Burke, unveiled at the Recorder of Deeds Building in Washington, D. C. in September 1945. Sinnock denied this and stated that he simply utilized his earlier design on the Roosevelt medal. giving a total composition of 91.67% Cu and 8.33% Ni. This composition was selected because it gave similar mass (now 2.268 grams instead of 2.5 grams) and electrical properties (important in vending machines)—and most importantly, because it contained no precious metal. The Roosevelt dime has been minted every year, beginning in 1946. Through 1955, all three mints, Philadelphia, Denver, and San Francisco produced circulating coinage; production at San Francisco ended in 1955, resuming in 1968 with proof coinage only. Through 1964 "D" and "S" mintmarks can be found to the left of the torch. From 1968, the mintmarks have appeared above the date. None were used in 1965–67, and Philadelphia did not show a mintmark until 1980 (in 1982, an error left the "P" off a small number of dimes, which are now valuable). To commemorate the 50th anniversary of the design, the 1996 mint sets included a "W" mintmarked dime made at the West Point Mint. A total of 1,457,000 dimes were issued in the sets, making it the lowest mintage Roosevelt dime up to that time. Since then, the "P" mint mark 2015 reverse proof dime and "W" mint mark 2015 proof dime, minted at Philadelphia and West Point for inclusion in the March of Dimes collector set, have the lowest mintages with 75,000 pieces struck for each.
