Editing Electrum (section)

===Early coinage===
The earliest known electrum coins, [[Croeseid|Lydian coins]] and [[Anatolia|East Greek]] coins found under the [[Temple of Artemis]] at [[Ephesus]], are currently dated to the last quarter of the 7th century BC (625–600 BC).<ref>{{cite book |last1=Kurke |first1=Leslie |title=Coins, Bodies, Games, and Gold: The Politics of Meaning in Archaic Greece |date=1999 |publisher=Princeton University Press |isbn=0691007365 |pages=6–7 |url=https://books.google.com/books?id=9eFxCAAAQBAJ&pg=PA6 |language=en}}</ref> Electrum is believed to have been used in coins c. 600 BC in [[Lydia]] during the reign of [[Alyattes]].<ref name="WM49"/>

Electrum was much better for coinage than gold, mostly because it was harder and more durable, but also because techniques for refining gold were not widespread at the time. The gold content of naturally occurring electrum in modern western Anatolia ranges from 70% to 90%, in contrast to the 45–55% of gold in electrum used in ancient Lydian coinage of the same geographical area. This suggests that the Lydians had already solved the refining technology for silver and were adding refined silver to the local native electrum some decades before introducing pure silver coins.<ref name="NC609">{{cite book |last1=Cahill |first1=Nick |last2=Kroll |first2=John H |title=New archaic coin finds at Sardis, AJA 109 (2005). |pages=609–614 |url=https://www.academia.edu/2465277 |language=en}}</ref>

In Lydia, electrum was minted into coins weighing {{Convert|4.7|g|oz}}, each valued at {{frac|3}} ''[[stater]]'' (meaning "standard"). Three of these coins—with a weight of about {{Convert|14.1|g|oz}}—totaled one stater, about one month's pay for a soldier. To complement the stater, fractions were made: the ''trite'' (third), the ''hekte'' (sixth), and so forth, including {{frac|24}} of a stater, and even down to {{frac|48}} and {{frac|96}} of a stater. The {{frac|96}} stater was about {{Convert|0.14|g|oz}} to {{Convert|0.15|g|oz}}. Larger denominations, such as a one stater coin, were minted as well.

Because of variation in the composition of electrum, it was difficult to determine the exact worth of each coin. Widespread trading was hampered by this problem, as the intrinsic value of each electrum coin could not be easily determined.<ref name="WM49">{{cite book|chapter-url=https://books.google.com/books?id=trkUDAAAQBAJ&pg=PA49|chapter=Asia Minor to the Ionian Revolt|last1=Konuk|first1=Koray|title=The Oxford Handbook of Greek and Roman Coinage|publisher=Oxford University Press|year=2012|isbn=9780199372188|editor-last=Metcalf|editor-first=William E.|pages=49–50|language=en}}</ref> This suggests that one reason for the invention of coinage in that area was to increase the profits from [[seigniorage]] by [[Debasement|issuing currency with a lower gold content]] than the commonly circulating metal.

These difficulties were eliminated circa 570 BC when the [[Croeseid]]s, coins of pure gold and silver, were introduced.<ref name="WM49"/> However, electrum currency remained common until approximately 350 BC. The simplest reason for this was that, because of the gold content, one 14.1&nbsp;gram stater was worth as much as ten 14.1&nbsp;gram silver pieces.
