That will be a 2 euro cents piece your talking about. Yes it does have a groove around the edge and it's made of copper-plated steel. The reverse design (the side with the number two on it) is the same on all 2 euro cent coins (with a very slight modification of the map of Europe after 2007) but the obverse will tell you which country issued it. Each country (originally 12 but now more) having its own designs. Now there's a set that will take some time to collect!
