a metal promise that's been bribing kings and tipping waiters for 2,600 years

means A small, flat piece of metal stamped with a value and issued as money, or the verb for inventing a fresh word or phrase.

from From Old French 'coin,' meaning a wedge or corner, which came from Latin 'cuneus,' a wedge — the same root behind 'cuneiform,' the wedge-shaped writing. The link is the stamping die: a wedge-shaped tool was driven down to strike the design into the metal, so the tool's name slid over onto the thing it made. The 'invent a word' sense grew from this image of striking something new into being, as if minting language.
