Lydien var det første land, der prægede [[mønt]]er af [[ædelmetal]]. Møntprægningen startede omkring 630 f.Kr.<ref>[https://www.worldhistory.org/article/1793/the-invention-of-the-first-coinage-in-ancient-lydi/ 09 July 2021, worldhistory.org: The Invention of the First Coinage in Ancient Lydia], [https://web.archive.org/web/20230415123515/https://www.worldhistory.org/article/1793/the-invention-of-the-first-coinage-in-ancient-lydi/ backup] Citat: "...There had to be a better way – and the ancient Lydians invented it...In approximately 630 BCE, someone in the Anatolian kingdom of Lydia stamped a piece of precious metal with something akin to a [[Signetring|signet ring]]. One outcome of this simple act was that it increased confidence in the lump’s weight and purity when later used in the marketplace. This procedure did nothing to modify the intrinsic value of the commodity, but it simplified the exchange of [[bullion]] for anyone willing to accept the [[Segl (mærke)|stamp]]’s guarantee [[Førstehåndsindtryk|prima facie]] rather than reweighing and retesting the lump every time it was traded...The stamps were rudimentary affairs at first, bearing messages in Greek or Lydian stating, "I am the [[signet]] of Phanes" or "I am [the seal] of Kukas." It must be remembered, however, that ancient peoples treated a [[Segl (mærke)|seal]] more formally than we do a [[Signatur|signature]]; the seal embodied the full power and prestige of the person associated with it..."</ref> Lydiens rigdom var berømt.
