Livre Tournois

The Livre Tournois wasn't a coin at all, but a unit of account that shaped French currency from the 13th century onward, representing a theoretical pound of silver divided into 20 sous or 240 deniers. This system, introduced under Louis IX around 1266, standardized transactions across a fractured medieval economy, making it easier to tally debts and taxes without the hassle of actual bullion. Coins like the denier tournois or gros tournois were minted to fit into this framework, but the livre itself remained abstract, more a bookkeeping tool than something you'd jingle in your purse. We're not sure exactly which years saw its peak use, as records from that era are spotty, though it persisted until the 18th century's reforms. Historians sometimes conflate it with physical currency, but that's just another myth I've debunked over the years—calling a unit a coin doesn't make it one. As for specifics, no mintage figures survive; they probably went up in smoke with some archive fire long ago. It's a dry reminder that not every monetary story involves shiny metal.
