The last line of the obverse is - Ayub b. Muhammad
Someday everyone can make mistakes.
Which is NOT clear to read ( if not impossible ) even for Arabic readers , but you figured the coin out from the first word of second line نجم which is
part of the
nick name of the ruler نجم الدين Najem al- Din , plus your experience.
Good job.
However, Joe is telling you what
Malloy said about the coin, not what Joe Sermarini said.
Also , I would not call
Malloy ‘s job , a mistake . I would call it an error, the
man was trying in language not
his first, yet
Islamic coins are hard to read specially in Bronze . If you miss one letter , the whole word can be different , I am sure you know that.
