Have you ever noticed that many first century denarii use a T style where the top bar is not one line but two short ones meeting in the middle leaving a small notch at the top? This photo is a Ttibute Penny of TI CAESAR. Check your coins and see if they agree.
Interestingly, the obverse of my Caligula denarius shows two Ts that both almost look like a flying bird (the Ts at 10 o'clock and 8 o'clock on the obverse) but the two Ts on the reverse appear fairly normal: GAIUS (CALIGULA) AR Denarius (3.68 g.) Lugdunum 37 - 38 A.D. RIC 16 C CAESAR AVG GERM P M TR POT laureate head of Caligula right. Obv. DIVVS AVG PATER PATRIAE radiate head of Divus Augustus right
The T in Pater has the notch. The one in Patriae shows enough that I do not believe the bar was made in one stroke.
In this denarius of Antoninus Pius, the top bar of the letter T does not look flat. To mention that this coin is from the early second century, and that Pius is venerated as Divos.
Cool coin search, Doug ... thanks for the treasure hunt Sadly, I don't have too many 1st century BC denarii with T's on 'em ... Ummm, looks like "T" in Titus has a sweet dip in it ... ... but my gorgeous Domitian example seems to have fairly normal lookin' T's yes?
this is my only first century denarius..i think the T is notched...but can't tell for sure. update: i got out that coin and looked at it with a loop, it does NOT have a notched T.
