I have a website on late Roman copper coin types of Valentinian I (AD 364-375) and later emperors. http://esty.ancients.info/ricix/ At the top I link to "What's New?" and that has not been updated for months until today. This is a fun area to collect because the history is interesting and the coins are among the least expensive of all ancient coins, while there are many rare types that can be found occasionally to keep you interested.
I enjoyed perusing the pages. I agree it's an interesting part of the history of the Roman Empire, leading right up to the fall of the western empire. Inexpensive coins with rich history; a good combination! Great links to references and even primary sources. Well done.
That page represents an enormous amount of work on your part, well-done! I've recently become more interested in the coinage of the Valentinian and Theodosian dynasties. I will definitely be referring to this page often.
