This is simply a HD replacement for the default Septim without breaking default design. I did not create the textures from scratch, I simply replaced the default with higher res of the coin. I did however remake the side of the coin to enhance the indentations along the side of the coin. There is a small spot in the texture I will have to fix, but for now this will suffice.
See screenshots for Before & After
Default install uses Lower BPP No Mimaps
I created versions with and without Mipmaps, though there should not be a problem using base install this is simply a precaution to prevent have to update for something other than an actual fix to the textures themselves.
The differnces between base install and the higher BPP versions is subtle.
