This made it a good place to set a standard weight for things like gold. Everyone could then agree on what a fair gold price should be.

Tracing the Roots to the French Trade Market of Troyes

The troy ounce idea might be older than we think. Some say the French used an Roman weight system as a starting point. They made their own standard weights from this. The Troyes market was always busy with trade and selling precious things. This activity helped make the troy ounce a widely used weight.
