well its worn but maybe something like this http://www.wildwinds.com/coins/ric/vespasian/RIC_0040.jpg http://www.wildwinds.com/coins/ric/vespasian/RIC_0028_2.jpg chins match
Most likely a denarius not a quinarius or aureus as suggested above. Edit: since the link keeps changing.
Vespasian has a bigger rounder chin than Trajan If not for that, I would have sworn it was a Trajan. they look pretty similar since its really worn the laurels kinda looked the same However, the shape of the head appears like Trajan( slimmer back of the neck) Vespasian was a chubby emperor.
