Thanks for the comments everyone. I am very interested in the variety of portraits in the coinage of Galba. I now have 6 examples including this one and not one looks anything like any of the others. I will say I am not convinced that this is unofficial given the huge variation in portraits and given the fact the CNG did not label it as unofficial. There is also the fact the times were very turbulent when this coin was minted and this might have had an affect on the minting of coins. For another example I would refer to the poorly struck lifetime portraits of Julius Caesar. Many scholars believe the coinage was poorly struck because of the tremendous pressure the mints were under to produce a large volume of coins.
