Hello experts!
I am unable to find the reference of this coin, it is in very bad condition:


There are some simmilar under Scotland but none with this weight and diameter
Weight: 1.35g
Diameter: 17mm
One side: HIB …
Other: MAG BRIT …O…
So I guess is CAROLVS

Anyone have a clue what reference is this coin?
Thank you for any comment
Geison
