ELECTRUM
For about 300 years, most "gold" coins were struck in this sometimes
natural alloy of gold and silver. Electrum continues to be a modern
coinage metal.

All of the 93 oldest known coins uncovered at the Temple of Artemis at
Ephesos are electrum. Electrum is an alloy of gold with silver and
traces of other metals. Natural and artificial electrum served as the
most common form of "gold" coinage until about 330 BC when
nominally pure gold coins from Philip II of Macedon, and his son
Alexander, flooded the Greek world.

Even after Alexander, electrum money continued. Carthage issued
electrum coins. So did the Roman emperor Severus Alexander as did the
Romaion ("Byzantine") emperors of Constantinople. A thousand years
later, in America, the United States Mint considered a "goloid"
electrum coinage. New electrum coins still appear on the market today.

Metallurgical Context

The definition of what is electrum is somewhat arbitrary. All
geologists agree that electrum is a naturally occurring alloy of gold
and silver, usually with measurable copper and trace residues of other
metals. Some geologists define electrum narrowly as being 35% silver
to 45% silver. For others electrum ranges in composition from 1% to
99% silver.

Gold-rich electrum occurs in sulfide-poor deposits. In such cases, the
range of gold is narrow. Copper (along with bismuth and tellurium)
occurs generally in gold-rich electrum. Silver-rich electrum occurs in
sulfide-rich deposits. The range of silver varies widely. Lead (along
with tin, zinc, and selenium) occurs in silver-rich electrum.

This part of the posting is very well-done. I wasn't aware of how much the
definition of Electrum could slosh around.

Thanks, Mike.
