The short answer
Some of the earliest known coins were made from electrum, an alloy of gold and silver, in western Anatolia during the seventh century BCE. Electrum occurs naturally, but some early coin alloys were deliberately adjusted. Croesus’s later gold and silver coinage did not mark the beginning of silver’s use as money.
A pale alloy at the beginning of coinage
The earliest chapters of coin history bring gold and silver together in the same object. Electrum is their alloy, and it was used for early coins associated with Lydia and neighboring Greek communities in western Anatolia, in what is now Turkey.
The exact beginning remains debated. The Metropolitan Museum of Art places the emergence of electrum coinage near the end of the seventh century BCE while acknowledging uncertainty about the date. Individual museum catalogues may give broader ranges: the British Museum dates one striated electrum stater attributed to Miletus to approximately 650–600 BCE.
Natural metal, sometimes adjusted
Electrum occurs in nature. The Sardis excavation project describes grains and nuggets recovered from streams in the Lydian region, including the Pactolus near Sardis. Its natural proportions of gold and silver varied, which presented a problem when the metal was used in exchange.
But “natural alloy” does not mean every electrum coin was struck from untouched natural metal. Crawford Greenewalt’s account for the Sardis project points to late-seventh- and early-sixth-century coins containing more silver than expected in the local natural material. That is evidence for deliberate adjustment of at least some coin alloys.
A collector should therefore avoid assigning one fixed gold-to-silver ratio to the word electrum. The term identifies the principal metals, not a universal ancient recipe. Attribution to a particular issue and reliable compositional evidence are more informative than color alone.
Why a stamp mattered
Numismatist John Kroll, writing for the Sardis excavation project, explains the advantage of stamped pieces made to recognized weights. Instead of individually testing and weighing every irregular piece of mixed metal, users could accept units backed by an issuing authority.
The earliest evidence is varied. Kroll discusses pieces from the Temple of Artemis at Ephesus, including plain or punched examples and coins bearing different designs. This was a developing practice, rather than a single surviving coin that can confidently be labeled the first one ever made.
For a modern observer, a modest punch or simple animal design can therefore carry substantial historical meaning. It helps connect a small piece of alloy to systems of weight, identification, and trust.
Croesus separates the coinage
In the sixth century BCE, the Lydian king Croesus introduced separate gold and silver coinages. Kroll describes this as a reform replacing electrum with a two-metal currency. The familiar lion-and-bull design appeared on the new issues.
The archaeological evidence at Sardis also includes installations used to separate gold and silver. This links monetary change with metalworking knowledge. It does not establish that every later electrum issue disappeared: the reform concerns a particular kingdom and coinage tradition, not an instant worldwide change.
Silver money is older than silver coins
The original fact card’s final leap needs care. Croesus did not introduce silver’s entire role as a monetary metal. The Bank of Italy’s museum describes Mesopotamian tablets showing silver used for exchange, accounting, and storing value from the third millennium BCE, long before these coins.
Coinage changed the form and organization of payments. It did not create every use of money from nothing. For collectors, that wider history makes an early silver or electrum coin more interesting: it belongs to a long story of measuring metal, trusting its quality, and recognizing the authority behind a mark.

Original source and editorial notes
Adapted from original material by Rich Silver. Original source card: Silver fact — supplied original card (publication date not established).
Reviewed 2026-11-04. Qualified the card’s absolute “first coins” wording with region and approximate chronology. Distinguished naturally occurring electrum from evidence of deliberately altered coin compositions; no universal alloy ratio is asserted. Retained the sixth-century Croesus reform with scholarly attribution, and corrected the implication that this introduced silver as money: silver served monetary roles long before coinage. No modern provenance, market value, or rights for a coin image are invented. The original card has no verified publication date or public URL; neither has been inferred from file metadata.
