Identification : looks like 1 Postulatsgoldgulden

Hi !
I have this coin (?)
very similar to https://en.numista.com/catalogue/pieces107924.html
Diameter = 23mm
Weight = 5,73gram

Any help will be appreciated !

Hello,
It's not on numista yet.
It represents a "postulatgoldengulden" of Jean de Hornes, Prince-bishop of Liege :
Observe : "+IOhS DE hORN EPS LEODIE"
Revers : "SANCTVS LAMBERTV"

Unfortunately, for me it's a copy : it should weight about 2,3g and the details are crude compare to the original (I don't like the lettering).

Indeed, it looks like a horner gulden. I didn't think it would be the real thing (I'm not that lucky), but it might have been something like a double gulden or so (because of the weight)
Let's see what others think.

Yes, looks a copy, perhaps made in 2005, commemorating the 550year dead of Johan van Hoorn
Scroll down here, there is a postulaadgulden:
