Pwill,
Congrats on the apparent rarity of your find !!
"Titus minted quite a flurry of coins after his father Vespasian's death in June of 79 AD. Many are quite common and are a continuation of themes and types issued under Vespasian. The left facing portraits from this series are much scarcer than right facing.
A Judaea Capta type (or perhaps a reference to a British victory?), this left facing portrait of the type is rated R2 by RIC. Normally the left facing types were issued at ratio of 1:10 against right facing, this one seems to have been minted on an even smaller scale."
