https://www.forumancientcoins.com/numiswiki/view.asp?key=Anonymous Byzantine Class A Folles Valentinian also dedicates to A2 class one page on his site: http://augustuscoins.com/ed/ByzAnon/ClassA.html What I found missing on both sources is the subtype of type 24 with IHSH / XRISTU on the first two lines on the reverse, instead of the standard IHSUS / XRISTUS. I could not find this variation referenced anywhere. I checked on acsearch the "IHSH / XRISTU" sold and checked on ebay for a few weeks. I believe that this type is not rare, because there were quite a few coins sold, although most were described as "IHSUS / XRISTUS", which makes their identification difficult. There are coins with clear border, so off-centered strike is out of question. It is clearly not a one-off die engraving error, because these were minted with several dies. I did not notice other A2 types, other than the type 24, with this exception. All coins have the same type of "A". Most seem to be around 8 grams. While checking online for specimens, I noted the first coin in the table below has 3 vertical dots on the book, which will make it alone a new subtype by the "ornaments classification rule". So, photos now. The specimens I found: The "standard" class A2, type 24: And the "exception": Any thought appreciated, as well as your pictures of the type.
