Hello,
In my small collection I have one coin that I cant identify 100%




I know it is a Belgium 5 Centimes, but the year is not certain. I think it is the version from 1861 - 1864 because that is the only one with squares in the side. The coin is 19.38mm in diameter and 1.33 mm thick.
the problem i have is the difference in the knee and tha upper part of the tail, they do not match in my opinion.

Who can help me?
