Detecting in North of France

Hey, first post. I bought a simplex BT from Nokta Makro and did a bit of detection in my garden. Found these, all ided but the one in the middle still a mystery…

also while I’m here might also ask about this non coin item, which I think is an anglo-saxon brooch from my searches

cheers,

Alex

 Maybe Spain or a colony of there, with castle and lion. 

Lions were also common all over Low Countries, including both Brabant and Flanders.  Seeing ROM (maybe?) made me think of Charles V, so possibly this?  N#153259

Interesting! Thanks you for your expertise, this seems to be the coin indeed.

note that the symbol if my city is indeed a lion, and that in Flanders indeed a lot of lions. (It’s in Flandres)
