After the reign of [[Marcus Aurelius]] (r. 161–180) the production of ''aurei'' decreased, and the weight was further decreased to <math>\tfrac{1}{50}</math> of a pound (6.5 g) by the time of [[Caracalla]] (r. 211–217). During the 3rd century, gold pieces were introduced in a variety of fractions and multiples, making it hard to determine the intended denomination of a gold coin.{{Cn|date=May 2014}}
The ''solidus'' was first introduced by [[Diocletian]] (r. 284–305) around 301 AD, struck at 60 to the Roman pound of pure gold (and thus weighing about 5.5 g each) and with an initial value equal to 1,000 ''denarii''. However, Diocletian's solidus was struck only in small quantities, and thus had only minimal economic effect.
