I have composed a stand-alone web page titled "Constantius' Gaul-Britain Coinage" (link in signature block) that is devoted to the various issues of folles produced in Gaul at an Unknown Continental Mint in preparation for the invasion of Britain and subsequently at the re-opened London Mint - and possibly other British Mints - during the lifetime of Constantius.

Thank you so very much, Q. As you can see I expanded the page into a mini-site titled "Romano-British Tetrarchic Coinage" (link in signature block) -- I simply couldn't do the subject justice on one page. James
