ID Of Ayyubid Coin

Plant's book is an excellent aid for identifying Islamic coinage, even if it does read a bit too much like my old school textbooks for comfort (after each chapter, he assigns homework!).

I've found two other books to be helpful: Stephen Album's "A Checklist of Islamic Coins" lists the known types and varieties for each ruler and dynasty, though it's got no pictures. The other is Album's reworking of the 1800's book, "Marsden's Numismata Orientalia Illustrata" - this has the pictures a non-Arabic speaker like me needs, with line drawings of many of the more commonly encountered types.

The best online resource is zeno.ru's Islamic pages. They've attempted to cross-index this with the Album numbers from the Checklist.

As for your coin, I'm stumped. If the number "1056" is a date, then it can't be "Ayyubid" - that dynasty didn't begin until 1169 AD. And I'm struggling to find a ruler named "Al Malik Al Nazir (or Nasir)" around that date. The style looks to me to be more Seljuq than Ayyubid, though Seljuq coppers aren't common, particularly early ones.

after hours of looking through the Islamic collection of the Fitzwilliam museum, I came up with the following information:
Kayka´us I (1210-19) (ruler)
no mint (mint)

Category coin
Name Fals (denomination)

Saljuqs of Rum (subsubseries)

I'm sorry, I forgot to say that I had taken my coin to be read by a friend of mine from Syria. He looked at it and started shaking his head. He concluded that he could not read most of the coin, specially the reverse, because, he thought, the person that did the calligraphy was not a native Arabic speaker. Even the word "Sultan" on the obverse, is spelled incorrectly. There were too many "mistakes" and careless placements of dots. If I am correct that the coin is from the Seljuqs of Rum, then my friend was correct. Any opinions?

Thanks Sap. What you say seems right to me. I've heard of mint masters losing their heads over metal content; why not over time delays? But, when Arabic is used in the 13th century for phonetic purposes to render Turkish, I'd guess that creates its own problems. The Kalima is one thing, but the names of the Seljuq Sultan is another. However, that's just me guessing.
Personally, I think this is one lovely coin!
