Can someone help me with this coin, it is a 2001 5 rupees from india. The coin that I think is an error is the one on the left. On a normal coin there are two raised rings on the rim that are on the outside of the design on the rim, but on the error one there is one and looks like it is missing a ring. Any help is great, Thanks
The security edge is impressed prior to the strike, most likely during upsetting. The reeding is generated during the strike. The coin on the left has the security pattern closer to one face. That's not too uncommon on these 5 rupee coins. It is an error, nonetheless.
