Mark Bird thinks it's a coin from Poland/Lithuania (the eagle) and the text refers to: "CASIMIR REX".
If anybody can confirm this, please do.
Thanks Mark
Mia Scris came with the ultimate answer: This is a 1 Solidus 1665 KM13 from Poland struck under Johann Casimis (1649-1668)

Hey Thanks a lot Mia.

Mark Bird believes this is an imitation of a ottoman coin. A Cu or brass coin with a thin layer of silver. He might be right: there are indeed some places where the silver is gone and where the cu/brass is vissible.
So, this one is not for in my collection.
Thanks Mark (again)
