Can some help identify this coin/coin weight please?

Can anyone help identify this?

It is 37.08 grams and 33 mm

It also has two initials on the side but I cant make out what these are.

Any help much appreciated

It looks like a modern object imitating a Bohemian Groschen.

Something like one of these:
