I can certainly add the Heritage
Auctions one, (I have permission from 99% of sellers and
auction houses)..
I think it would be an impossible task to add every known imperial coin to
wildwinds, for one thing the server space required would probably double the server costs, which I am already struggling to cover. I have managed to save some space to add different coins by deleting a lot of the superfluous examples (e.g. "21 examples" on some early emperor pages), as most of the examples were from the late 1990s and tiny or illegible or incorrect.
