I have updated my Roman Inscriptional Lettering page that I hope collectors will find of some use when reading the legends on their coins. There are numerous excellent photographic exemplars, mostly accompanied by translations and analyses, via the link to Bill Thayer's Roman inscriptional pages. James
It looks like you put in quite a bit of time researching this topic. I don't collect ancients but this info should prove helpful to those that do collect them.
Today I updated my Roman Inscriptional Lettering page to include several more exemplars and additional information. James
