[[File:Aureus Septimius Severus-193-leg XIIII GMV.jpg|thumb|300px|Aureus minted in 193 by [[Septimius Severus]] to celebrate [[Legio XIV Gemina|XIV ''Gemina Martia Victrix'']], the legion that proclaimed him emperor.]]
The '''aureus''' (pl. '''aurei''' — "golden") was a [[gold coin]] of [[ancient Rome]] valued at 25 silver [[denarius|denarii]]. The aureus was regularly issued from the 1st century BC to the beginning of the 4th century AD, when it was replaced by the [[solidus (coin)|solidus]]. The aureus is about the same size as the denarius, but is heavier due to the higher [[density]] of [[gold]] (as opposed to that of [[silver]].)
Before the time of [[Julius Caesar]] the aureus was struck very infrequently, usually to make large payments from captured booty. Caesar struck the coin more frequently and standardized the weight at <math>\tfrac{1}{40}</math> of a [[Roman pound]] (about 8 [[gram]]s). Augustus tariffed the value of the [[sestertius]] as 1/100 Aureus. The mass of the aureus was decreased to <math>\tfrac{1}{45}</math> of a pound (7.3 g) during the reign of [[Nero]].
