The Trier Gold Hoard is a hoard of 2516 gold coins with a weight of 18.5 kg, found in Trier, Germany, in September 1993 during construction works, nearly 1800 years after it was hidden. It is described as the largest preserved Roman gold hoard worldwide.
Greater inspection revealed that it was not simply someone's personal fortune but most likely an official treasury. The treasury had been carefully administered and had grown over time. The Hoard equated to the annual salary of around 130 Roman soldiers.
The aurei (gold coins) feature a total of 27 emperors, empresses and members of the imperial family, and some are still considered unique to this day. The gold coins were buried in a cellar during a civil war in 196 AD.
