As observed in RIC II.1, Page 170, note 67, this coin is presumed to be a mule with a Vespasian reverse as yet unattested to Vespasian. However, as noted for lot 581, other possible mule issues from the mint at this time are probably not mule. It will be interesting to observe f other example come to light in the future.
