Hello CCF members!
Hopefully someone who is very familiar with Indian coins could help with me this issue—2007 5 rupee coin.
I couldn't find any information on its security edge.
I do believe I have a mule according to this page on Numista:
https://en.numista.com/catalogue/pieces5021.htmlBut the problem is that my coin has a very small part on its edge where it shows it is crude or something like it is being stepped on? I do not see any information on this specific part of the coin itself?
I would love to upload the photo or two but I do not know how to take a photo of the edge without touching the sides of the coin?

I do hope it is not a fake which is sadly common in India now.
Many thanks for your help in advance,
Carrigna
