Mercury Dimes with Full Bands (or FB) detailing show whole horizontal lines in the crossbands of the fasces, which are part of the major design on the reverse of the Mercury dime. These dimes were manufactured from 1938 to 1958.
FB dimes are more common than those with half bands (HB). The difference between the two varieties is based on how much of the field on the reverse of the coin is used for design elements. If a large portion of the field is occupied by such elements, then the coin is called full banded or FB. Otherwise, it is called half banded or HB.
The first Mercury dimes released in 1938 had HB designs. However, these coins were struck in pairs at the San Francisco and Philadelphia mints from sets purchased by the government for use as war savings stamps. Therefore, they have very low mintage numbers and are highly prized by collectors.
The 1939-1945 issues also had HB designs but these coins were produced in large quantities for use as trade dollars. They are less rare but still valuable because of their connection to the wartime economy of the United States.
From 1946 to 1957, all Mercury dimes had FB designs. These coins were produced in large quantities for use as circulating coins and as filler in Gold Dollar rolls.
The major lines in mercury have wavelengths of purple (405 nm), blue (436 nm), blue-green (492 nm), greenish yellow (546 nm), yellow (577 nm), orange (623 nm), and red (691 nm). Keep in mind that 1 nm equals 10-9 m. Therefore, 1 cm is 10-3 m and 1 mm is 10-6 m.
These colors are produced by the mercury vapor in its lowest energy state, which occurs only at very low temperatures. At higher temperatures, it enters a more stable state, which produces white light when sunlight is passed through mercury vapor. The color we see is mainly due to the presence of two different elements: mercury and argon. Argon has four electrons in its outer shell and so does not emit or absorb light, whereas mercury has 80 electrons in its outer shell and so emits light in the ultraviolet range and also absorbs light in the violet and blue ranges.
Because mercury is used in some optical instruments, it is important to know its wavelength. The color of mercury vapor is dependent on its temperature. It appears violet to red at low temperatures and becomes white at high temperatures. However, for most applications where color accuracy is not critical, it can be considered blackbody radiation at room temperature, with a peak emission at 545 nm and a peak absorption at 400 nm.
The wavelength of mercury vapor is strongly dependent on temperature. It decreases as temperature increases.
This Complete Mercury Dime Set Album, 1916–1945, is a must-have for every type of collector. The set contains 77 Mercury Dimes, each weighing 0.07234 troy oz and crafted of 90% pure silver. In addition, the collection includes a 1916 D Mercury Dime graded Fair 2 by NGC. Lady Liberty has a winged Phrygian hat on the obverse. On the reverse is an eagle with outstretched wings and wreaths on its tail and head. Above its left eye is a five-pointed star and below its right eye is a circle with a dot in it.
The story behind these coins begins in 1915 when President Woodrow Wilson asked Congress to create the United States Mint for the purpose of producing gold and silver coins that could be used as currency. These coins are called "dollars" and "minutes." The word "dollar" comes from the Spanish dollar, which was originally made of silver but now mostly of copper.
These Mercurys were produced from 1916 to 1918 by the United States Mint at San Francisco. Each coin was designed by Charles E. Barber, who also designed the Lincoln Memorial, Washington DC. The motto ONWARD AND UPWARD appears in the center of each coin's field.
These coins were minted in three sizes: 5 cents, 10 cents, and 25 cents. Each coin was assigned a unique mintage number by the San Francisco Mint.
The Mercury Dime had the same specs as the previous series, with a composition of 90% silver and 10% copper. Each dime is 2.50 grams in weight, 17.9mm in diameter, and has a reeded edge. They were produced from 1975 to 1978 by the United States Mint.
The price of gold increased dramatically during this time period, which caused production costs to rise. In an attempt to remain competitive, the mint reduced the quantity of silver in each coin while maintaining the original weight. This resulted in dimes that are less dense but still have the same face value as before. The mint also changed the design on some of the coins to make them look newer. These modifications are most evident on the 1976 and 1977 dimes; the 1975 coin should not be used for valuing jewelry.
Dimes were sold in cartouches of 25 pieces and bundles of 100. Each bundle contained five coins of the same year but with different designs. For example, one bundle might contain one 1975 dime, one 1976 dime with the revised design, one 1977 dime with the modified design, and two 1978 dimes.
There are several varieties of dimes available including proof, commemorative, and ancillary. Proof dimes are pre-mirrored coins that are polished to a brilliant shine for display in the hand or on a wall.
A dime of mercury (1916-1945) Mercury dimes are ten-cent coins issued by the United States Mint from 1916 until 1945. The composition of this dime is 90% silver and 10% copper. It weighs 11 grams and has a diameter of 25.5 mm.
Mercury is a soft, malleable metal that is easily bent. In fact, it will naturally bend while you work with it because its melting point is so low (78.5°C or 167°F). It is used in thermometers, barometers, and other instruments because of its property as a conductor of heat and electricity.
These days, people often use the term "mercury" to describe any type of coin that is composed primarily of mercury. But originally, these coins were called "dime pieces" because they were valued at $1 and contained 10 ounces of silver.
This is because ancient astronomers used mirrors and telescopes made of glass or bronze, which are both compounds of mercury, to view stars and planets beyond the Earth's atmosphere. The first known written reference to mercury was in the Iliad, which was written about 800 BC.
The ground state electron configuration of gaseous neutral mercury is [Xe]. 4f14. 5d10. 6s2, and the term symbol is 1S0. Neutral mercury has a molecular weight of 197.894. The atomic number is 80. The atomic mass of mercury is 200.01.
Mercury has two inner electrons in its valence shell, which means it is an element with a partially filled d-shell. Because of this, mercury can form several chemical compounds that contain mercury atoms only. The most common compounds are HgO and HgS. Mercury is a soft metal that easily oxidizes. It is insoluble in water but soluble in organic solvents such as benzene and chloroform. When exposed to air, mercury becomes toxic due to formation of reactive molecules called mercuric ions.
In chemistry labs, mercury compounds are often prepared by heating elemental mercury with appropriate reagents. This reaction releases hydrogen gas, so you need to be careful not to let the mixture explode.
The most common use for mercury is in thermometers. A thermometer that uses mercury to sense temperature needs to be replaced every time you replace a part of the thermometer. Otherwise, you might end up using a contaminated thermometer reading false information about the temperature.
