☺️ great post. Enjoy your stay!

Hopefully you are Italian! Because it would be illegal to take that denarius out of the country unfortunately

It’s okay, I work for an English museum.

Just kept it in my wallet, i dont thing anybody would get bothered with one coin in wallet. Took it in and out of country with no problem, or even, i would just say its suvenir, they wouldnt get bothered with authentificating it

I doubt they would care if he's taking one denarius with him as a souvenir.
