Slovenia, which you registered as your home country, is in the Euro zone since 2007.
By now, you should know that this 'grooved edge' is the normal edge for any €0.02 coin in the entire Euro zone.
I know maybe it looks normal to you. But i looked close enough to see that the inside edge is deeper than normal i compared it to the exact same 2 cent coin and there is a really small difference. Its true that i have never noticed a double edge on a coin before but this one is still a small bit different. Thanks for the reply
