I agree with Eduard. The emperor is unmistakable. Gotta love that ugly mug, it always reminded me of Ed Asner.
Yes - I have a similar one at present. Looks better in the hand than these scans suggest, but definitely Vespasian. Always interesting to those of us living in Dorset as Vespasian as a General was responsible for the capture of Maiden Castle from the indigenous Brits. That extraordinary fort is only a few miles from here. See http://www.dorsetaonb.org.uk/assets...Resources/Image_bank/Maiden_Castle_Aerial.jpg for what an impressive structure it is.
Sometimes it helps to see a slightly better example so you can identify the parts shown. http://www.acsearch.info/record.html?id=599857
