Coinage, beginning with Lydia's coins about 630 BC

Around 630 BC the kingdom of Lydia, in today's western Turkey, began stamping lumps of precious metal into coins.
See it on the Money & Finance map →How it works
Lydian coins were made of electrum, a natural gold-silver alloy from local rivers, stamped with a lion's head. The stamp vouched for weight and purity, so people could count coins instead of weighing metal. King Croesus (ruled about 560–546 BC) is traditionally credited with separate pure gold and silver coins. Greek cities copied the idea quickly. China (bronze spade and knife money) and India (punch-marked silver) developed coins in the same era, apparently independently.
Why it matters
Coins made payment portable, countable and trusted, helping trade, taxes and paid armies spread across the Greek and Persian worlds.
Facts, rules and data
Herodotus (about 430 BC) wrote that the Lydians were the first to use gold and silver coins. Early electrum coins were excavated at the Temple of Artemis at Ephesus.
Debates and risks
Exact dating is debated (about 650–600 BC), as is whether coins first served trade or rulers paying soldiers and collecting taxes.

▸Commodity money: shells, salt, grain, cattle was standardized into Coinage, beginning with Lydia's coins about 630 BCFact, law or data
The connection
Lumps of metal were already used as commodity money, but each payment meant weighing and testing purity. Lydia's stamped coins fixed weight and purity in advance, so metal could be counted rather than weighed. Coins turned a raw commodity into a standard, trusted unit.
When and why
Lydia, western Turkey, about 630 BC; the idea spread to Greek cities and Persia within a century.
How we know
Archaeologists find both earlier hacksilver hoards (cut silver weighed in payment) and the first coins, showing the transition.
Debates and risks
Whether coins first spread for market trade or for state needs, like paying soldiers, is still debated.
▸Coinage, beginning with Lydia's coins about 630 BC began the tradition continued by Bureau of Engraving and Printing and the US MintFact, law or data
The connection
Lydia's stamped metal pieces introduced the idea that an authority guarantees a coin's weight and purity. The US Mint inherited that tradition: the 1792 Coinage Act set a decimal dollar modeled on the Spanish silver dollar and made coin-making a federal job, as the Constitution bars states from coining money.
When and why
Lydia, in western Turkey, about 630 BC; Philadelphia, 1792, when the Mint opened under director David Rittenhouse and struck its first coins.
How we know
Lydian electrum coins found at Ephesus and Sardis; the Coinage Act of April 2, 1792; Mint records of the first 1792 half dismes and 1793 cents.
Debates and risks
A popular story says the first half dismes used George Washington's household silver, probably a legend. Some scholars think Ionian Greek cities coined as early as Lydia.
