Title is incorrect. This is DIOCLETIAN but I can't find out how to change the title. There is a subset of coins from this issue at Trier that have a H under the bust. Coins with the H seem to be somewhat scarcer than those without. Has anyone seen anything as to what this H might mean or indicate? I have not been able to find many.

To answer this question, I'd first want to see other coins. How certain is the reading H? Are there any other coins of the period from this mint that have any symbol there? If that is a I, then I might read yours as II. If B, yours could be an A. There is a note in RIC suggesting that some portraits of the mint remind them of Lugdunum style. I could see a mark like this indicating a die prepared elsewhere. I know nothing and this is not a specialty of mine. I do not see this as an easy answer. I only have one Trier Diocletian at all similar and it is certainly not pertinent but still fun to show.
Here are a few that I have been able to track down on Acsearch Constantius I https://www.acsearch.info/search.html?id=755001 Max. Herc.
