For Khusru II, there is a separate entry for Yazd Mint, Type II/2 and the other mints, Type II/2. However, Yazd Mint is still listed under the entry with all the mints, so it appears that you could catalog the same coin in two different pages.

I don't know much about Sasanian coins so I didn't want to make a catalog modification myself, but I feel that the YZ/YZD entry in #2 should be deleted, as it has already been separated out into the first entry. It seems these are the same type, but maybe I'm missing something.
