Silver standards refer to the standards of millesimal fineness for the silver alloy used in the manufacture or crafting of silver objects. This list is organized from highest to lowest millesimal fineness, or purity of the silver. Fine silver has a millesimal fineness of 999. Also called pure silver, or three nines fine, fine silver contains 99 ...
The Spanish silver dollar created a global silver standard from the 16th to 19th centuries. The silver standard[a] is a monetary system in which the standard economic unit of account is a fixed weight of silver. Silver was far more widespread than gold as the monetary standard worldwide, from the Sumerians c. 3000 BC until 1873.
The French have two standards for silver purity or fineness. The higher is 950 parts per thousand, or 95% silver referred to as 1st Standard. The lower grade of silver is 800 parts per thousand, or 80% silver referred to as 2nd Standard. Both standards are marked with the head of Minerva inclusive of a numeral 1 or 2 to indicate the standard.
Sterling silver. Sterling silver is an alloy composed by weight of 92.5% silver and 7.5% other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925. Fine silver, which is 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength.
The data below tabulates standard electrode potentials (E °), in volts relative to the standard hydrogen electrode (SHE), at: Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). Variations from these ideal conditions ...

Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver', derived from Proto-Indo-European *h₂erǵ'shiny, white') and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. [ 8 ]
Large-size silver certificates, generally 1.5 in (38 mm) longer and 0.5 in (13 mm) wider than modern U.S. paper currency, (1878 to 1923) [nb 1] were issued initially in denominations from $10 to $1,000 (in 1878 and 1880) [4][5] and in 1886 the $1, $2, and $5 were authorized. [5][6] In 1928, all United States bank notes were re-designed and the ...
