for your information
Roman rulers were allowed to produce only coins during the period that they were in power, some emperors were then also sometimes make coins with the effigy of their wife or daughter
by this fact we can perfect the dating period when these coins are made than, other currencies can be dated to the year perfectly (don't ask me how they know this so sure)
For exemple foto 1 : Emperror Septimius Severus, coin type : Sestertius, 30mm, 18.49 gr. Struke in 195 after Christ

Struke between 161 and 169 after Christ, Annia Aurelia Galeria Lucilla or Lucilla was a member of the Aurelii,
the daughter of Marcus Aurelius, Lucius Verus's wife and sister of Commodus.
Lucilla was born as the second daughter of Marcus Aurelius and Faustina the Younger.

That way we are now sure that all my coins from this treasure are dating back to the full 2nd century
