Another club dig near Shoreham today. Plenty of WWII munitions from a firing range and a 1912 halfpenny for my efforts. One of our members had a good day, 3 Roman including his first denarius above.
I have now identified this as Emperor Vespasian, AD 69-79. The obverse has the letters VESP + AVG (for Augustus, meaning Emperor) + CENS (meaning Censor Perpetuus refering to the Emperor's permanent holding of the old Republican office of Censor. The Censor had the power to rule on who was entitled to be a Roman Senator).
