I've just added the coin at the bottom to my collection and it appears to be a new addition to my listing of the three emperor coins of Carausius.
Although the dealer image is poor the coin is clearer in hand.

It has been over two years since I first published my catalogue of the three emperor coins (updating Carson's catalogue in the 1981 Naster festschrift), available for download here:http://www.carausius.hookmoor.com/home/wp-content/uploads/2011/11/Bourne-Article-from-Editorial-Dec-09.pdf
I now have over twenty additional varieties and a supplement is close to publication. Can I take this oportunity to solicit any last minute additions to that listing please.
