But let's focus instead on the common point between these two pieces. You surely noticed they both featured the goddess Libertas; and also that she is holding in her right hand a pileus. Let's talk a bit about this famous hat and its origin. First, the title of this thread is rather inaccurate, the pileus having a Phrygian's origin. It was a soft woven wool cap often associated with the notion of freedom( that's why Libertas is holding it). The pilei was found in several form: often round, sometimes looking like a helmet, even shaped almost like a pyramid. The pileus originated in Greek iconography as the hat of the Dioscuri, the twin sons of Zeus, Castor and Pollux. Their peculiar hats were supposed to be the vestige of the eggs from witch they were hatched. Roma, piazza del Campidoglio Odysseus, the legendary Greek king of Ithaca and the hero of Homer's epic poem the Odyssey, is usually depicted wearing the famous pileus. Museo Archeologico Nazionale di Napoli For the Romans, it was also a symbol of freedom. In the republic, during the ceremony of enfranchisement, a slave was given a pileus to wear as a public sign of his freedom. The most popular example is obviously the cap of liberty on Brutus' Eid Mar coins. The message was intended to convey that on the Ides of March, Brutus set the people of Rome free.

At least 20 emperors has this specific iconographic element on their coinage. Now it's time to show of your coins. Please present us your Pileus' examples!
