On the dupondii of Domitian as Caesar, minted during the reign of Vespasian and Titus, there is a bust without a radial crown - in this case, the high weight and visible yellowish color of the metal, i.e. orichalcum, from which the coin was made, give us certainty as to the denomination.
Coin missing in the collection of the British Museum.
