Sorry for all the post this will be my last for now. I know it’s a German states coin of some type but what I do not know the key on the obverse reminds me of a Becks beer so I’m assuming it may be from that same area lol
Diameter: 16mm
Weight:0.7g
sounds like it may be billion since it has a silver sound to it
Yes, I thought it could be that coin, with the diameter and the date,
but that has MONET NOV and this has MON NOV lettering.
Just added a few letters that are most visible.
