The coins of Lydia were made of electrum, which is a naturally occurring alloy of gold and silver, that was available within the territory of Lydia. [103] Since that time, silver standards, in which the standard economic unit of account is a fixed weight of silver, have been widespread throughout the world until the 20th century.
Silver mining required large amounts of mercury to extract the metal from ore. In the Andes, the source was the Huancavelica mercury mine; Mexico was dependent on mercury from the Almadén mercury mine in Spain. Mercury had a high adverse environmental impact. [26] Silver was extremely valuable in China, and became a global commodity.
[5] [6] Various amalgams of silver and mercury or other metals and mercury do occur rarely as minerals in nature. An example is the mineral eugenite (Ag 11 Hg 2) and related forms. [7] Silver nuggets, wires, and grains are relatively common, but there are also a large number of silver compound minerals owing to silver being more reactive than gold.
The rapid expansion of silver production and coinage—made possible due to the invention of amalgamation—has often been identified as the primary driver of the price revolution, a period of high inflation lasting from the sixteenth to early seventeenth-century in Europe. Proponents of this theory argue that Spain's reliance on silver coins ...
The alloy's natural malleability is an obvious physical advantage, but it is also naturally aseptic. [20] Some brasswind instrument manufacturers use 92.5% sterling silver as the material for making their instruments, including the flute and saxophone.

Naturally occurring silver (47 Ag) is composed of the two stable isotopes 107 Ag and 109 Ag in almost equal proportions, with 107 Ag being slightly more abundant (51.839% natural abundance). Notably, silver is the only element with all stable istopes having nuclear spins of 1/2.
