What coin is this? I can’t read the language :( [opgelost]

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

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
