Hi, I had a look at the four pages.
1. Pages #295445 and #160442 could be merged keeping as much as possible of the information in page #295445. When they are merged I will update the page following the zeno.ru structure. I will start with al-Mansur as it is now the one being discussed. Eventually I will do the same for other rulers.
2. According to Numista guidelines the name of the ruler should be in the title only if the name is present on the coin. For al-Mansur, and many other rulers at this time, the names are not on the coin. As long as the coins have the same design I will also add other mints to the page. The main title will be “Dirham - Anonymous”. The other 3 (or 4) titles will have a short description of the design within brackets, eg. “Dirham - Anonymous (citing al-Mahdi)”. For al-Mansur there will be 4 pages (maybe 5), based on design, and each page will have 2, 3, or 12 mints. I will also create a date line for each date per mint. For the largest page (anonymous) there will be maybe up to 100 rows. If this is considered too many the alternative is to create several anonymous pages based on mints, i.e. 12 pages.
3. Page #150131 is wrong. No coins were minted in Al-Muhammadiya in the year AH 143. Source is Steven Album Checklist and zeno.ru. When reading the text on the picture of the coin I am pretty sure it is written al-Basra. Al-Basra was producing coins in AH 143, so it does fit. I could update the wrong information on this page, however, I would prefer if this page is merged with the two previous pages (#295445 and #160442).
4. Page #81284 has a different design. Should be kept as it is. I will make some updates to the page for more details and clarification.
