Hello and welcome to Numista!
You have 3 very important pieces of information, the year, denomination and regal year.
Denomination (40) top, year (1327) bottom. Using that in a search gives 4 results: https://en.numista.com/catalogue/index.php?r=&ct=coin&im1=&im2=&tb=y&tc=y&tn=y&tp=y&tt=y&cat=y&ru=&ca=3&no=&v=40&i=&b=&d=&u=&a=1327&dg=&m=&f=&t=&w=&mt=&g=&se=&c=&wi=&sw=
Looks to be one of the 2 first results. The regal year is 8 (your picture is upside down).
Only the second one has regal year 8 (and is non-magnetic): N#7864
Islamic numbers translations can be found here: https://en.numista.com/numisdoc/calendar-islamic-30.html
That's the way to go. The OP might have learned something, if he's willing to learn. Anyway it's much better that just giving the solution with a link to the coin.
Bravo
