On the long cross side, two of the quarters may have MON and ETA lettering,
for MONETA meaning money. Not sure about the others six letters - but ... https://en.numista.com/catalogue/pieces96109.html
they could be MER and AVD perhaps - like in that coin.

Something like this >
where I started with straight lines for those fairly visible (orange) letters then
within all that added modern lettering - plus unsure (green) letters.
Not much lettering readable on obverse - but at top with the fancy cross -
there is that IOH lettering after it, there is a Bbefore it, like on that coin.
So I reckon that is what your coin is - around 700 years ago from Luxembourg.
Definitely the right one!
There are a number of subtypes with different obverse legends, but I think we can see IOhAES ..... EX B, which looks like @ZacUK's attribution.
There were official issues imitating the design of English pennies all over the Low Countries and parts of Feudal France. If I am not mistaken, Brabant, Flanders, Hainaut, Luxembourg, Namur, Lorraine and some other places all issued coins like this. We have many of them in the catalog.
