Need help with identification - probably copper - maybe French?

Need help with identification - probably copper - maybe French?

about 0.75 gram

about: 17 mm

 On right of first picture is ROLVS so probably the 

rest is the lettering CAROLUVS for Charles in Latin. 

 Still trying to find it - and KAROLVS could also be  the spelling. 

 What looks like I K monogram with something above, in an inner circle, 

with CAROLVS / KAROLVS on the right. 

 Inner circle with a thick cross, and a smaller shield on it - something in the 

middle and each corner has part of a circle. No lettering seen.

 There was I K crowned [each letter] monogram 

Belgian States › Brabant, Duchy of 

Iohanna Et Karolus 

Joanna and Charles 

 but not with a shield on the reverse. 

 That reply just seen above mine is almost right - 

except it is just a K crowned not I K and the shield is larger. 

 It is though Spanish Netherlands like I just mentioned. 

thank You so much for help ! 

I'm not sure the first character in IK is an I. It's thicker on top and reminds me of the shape of some denominations in the early 17th century.

Here's one example, but the top is thicker on the left instead of the right.

I also tried rotating the left image 180 degrees but that didn't look right.
