Troy and Avoirdupois weight are both European in originand the coin prpbably predates them by at least 1,000 years.

However the troy ounce is based on the Roman weight system where a troy ounce equaled a unit called a "uncia" which was 1/12 of a "aes grave" (troy pound). That system of weights dates to at least 289 BC.
I have no idea where the Romans got it from but it probably was based on something older yet.
