The figures cited in the tables are representative of the series, and are generally the latest, or most common, figures for a given coin type. The largest coin ever minted by the US Mint was the 2019 Apollo 50th anniversary 5ounce silver dollar, weighing 155.517 grams, and 76.2 mm in diameter. [5]
The eagle is a United States $10 gold coin issued by the United States Mint from 1795 to 1933. The eagle was the largest of the five main decimal base-units of denomination used for circulating coinage in the United States prior to 1933, the year when gold was withdrawn from circulation. These five main base-units of denomination were the mill ...
2021–present. The American Gold Eagle is an official gold bullion coin of the United States. Authorized under the Gold Bullion Coin Act of 1985, it was first released by the United States Mint in 1986. Because the term "eagle" also is the official United States designation for the pre-1933 ten dollar gold coin, the weight of the bullion coin ...
The dime is the smallest in diameter and is the thinnest of all U.S. coins currently minted for circulation, being 0.705 inches (17.91 millimeters) in diameter and 0.053 in (1.35 mm) in thickness. The obverse of the current dime depicts the profile of President Franklin D. Roosevelt and the reverse has an olive branch, a torch, and an oak ...
Vernier scale. Vernier caliper scales; main at top, vernier at bottom. It reads 3.58 ± 0.02 mm by adding 3.00 mm (left red mark) on the fixed main scale to vernier 0.58 mm (right red mark). The main scale reading is that to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the ...
Morgan dollar. The Morgan dollar is a United States dollar coin minted from 1878 to 1904, in 1921, and beginning again in 2021 as a collectible.

It has a diameter of 0.955 inch (24.26 mm) and a thickness of 0.069 inch (1.75 mm). Its current version is composed of two layers of cupronickel (75% copper, 25% nickel) clad on a core of pure copper. [2] With the cupronickel layers comprising 1/3 of total weight, the coin's overall composition is therefore 8.33% nickel, 91.67% copper.
In SI units, the values of c, h, e and k B are exact and the values of ε 0 and G in SI units respectively have relative uncertainties of 1.6 × 10 −10 [16] and 2.2 × 10 −5. [17] Hence, the uncertainties in the SI values of the Planck units derive almost entirely from uncertainty in the SI value of G.
