Hello Allain I ,
I am not an expert in this
type of
Islamic coins but I can
help you with this :
The Kuffi letters and
writing are a little ' funny '
Like :
1- bi Wasit in Kuffic ( in Wasit ) the “S” has 3 vertical lines . as in بو ا سط
In your coin 4 lines which is wrong .
2 – the word Year or Sanat is also wrong in your coin. the T the last letter in the word Year or sanat is wrong.
3- Allah alone ( Allah Wahdaho ) also is wrong .
And other language and grammar mistakes.
Welcome to
FORVM ,
Sam
PS ; here is an example of the Arabic letters
type used in that time .
You may like to compare Wasit and the other things I told you about.

like these.
