I usually spend an hour or two every night looking for coins others missed or perhaps did not want. I always check the unsold lots from auction houses you never know what you might find. I will be the first to admit that this is an ugly coin. However, it is also unique so far. This coin is the only one known. I love finding rare Flavian coins and I am always on the lookout for Dattari plate coins. Turns out this coin satisfies both. I have seen and ogled many Alexandrian coins with the Canopic reverses. I find this and other reverses on these coins to be interesting. Yes @TIF I blame you for this (thanks). Just read the history of this coin below in the attribution.

REALLY cool catch!!! Man, ole' Vespy looks like he spent all nite at the bars! Little bit of fightin', LOTSA drinkin', and a nasty lookin' hangover for that cameo! Yummy Obol! Gosh, since that is one-of-a-kind, that makes it FLEUR-de-COIN!
The portrait is still clear enough that I would immediately guess that it depicts Vespasian even if you hadn't said so.
