'another cracking little coin. It is the biga type as you say, still quite rare: we have just over 20 of the quarter recorded. I had hoped to have a look at the dies in comparison to the rest of the coins in Oxford this morning, but ran out of time and I'm now back in Guernsey again. That'll have to wait a while, but in the meantime it looks as though it's one of the later strikings of this type, because of the simplified CAMVL inscription on the obverse. The earliest examples have each letter very clearly defined, but they soon merge into what looks almost like a zigzag on some coins.
Saying it's a 'late striking' is all relative of course: it's possible that the biga type was struck over a very short period, perhaps even just months and certainly unlikely to be more than say five years or so, sometime around 8 - 13 AD I would estimate. It'll be CCI 05.0688
