Some of these larger groupings of issuers could fit under more generic ones (like the Islamic or Hindu dynasties); however, I do not think we can yet create fifth-level issuers, so I think this type of organization would work best with our fourth-level issuers.
For the already existing issuers, most do require edits. Some are minor and are for consistency (like de-capitalizing “Dynasty” or changing names from “Bengal, Sultanate of” to “Bengal Sultanate”--keeping all items of those titles the same throughout all of India/Ancient India/Islamic States). Some edits are major because the issuer is too generic, and the coin currently under those issuers will be sorted into more appropriate sub-divisions.
When I created that list, Numista was only in English and French, and the above Sheet reflects that. I cannot help much with the other languages which have been added.
And for any place without coins currently on Numista, I will add their coins after the issuer is created.
Thoughts/comments/suggestions are welcomed, of course. x)
