This coin is a contemporary forgery. It was made with a copper flan covered with a thin covering of silver, before being struck. The copper can be seen poking through the silver in places. Although the obverse is of Domitian, the reverse is of Vespasian, i.e. a hybrid. In theory, this coin could have been made any time after 69 AD.
