The Lucilla was indeed nice. It had a sweet portrait. I think she looked better in that portrait than on some other coins. (If memory serves, that was a ~$200-ish coin.) An interesting thing about Roman coins is how much the portaiture can vary, even within the exact same type of coin. There was a Lucilla thread here fairly recently, which I posted that coin to. Look at the range of portraits. Some are slightly frumpy, some look grumpy, others look glamorous. To cite another example, I've heard it said that the coin portraits of Caracalla are like The Picture of Dorian Grey. He starts out young, fresh-faced and innocent looking, morphs into a hard-faced mature man, and finally ends up as the scowling tyrant.
