A user on the Nexus Forums pointed out a minor issue with the image on the gold coins used throughout the game. Most imperial dynasties made sure the current emperor's image was on the face of their coins and since the Empire in TES V is really not much different from a Roman dynasty, he wondered why they had not used Titus Mede's face. His thread can be found here: https://forums.nexusmods.com/index.php?/topic/7650528-a-matter-that-was-never-adressed-tiber-septim-on-imperial-coins/
I made an inquiry about how easy this would be to address and the results are in - Titus Mede is now on the front of the Imperial currency. His image is based on his NPC record in the game data.
Unfortunately because the term "septims" is heavily used in a lot of spoke dialogue, this only replaces the texture on the coins but doesn't stop the people from continuing to call them Septims. Somehow this actually seems appropriate given the political climate in Skyrim in 4E 201.
