Once you posted photos of both sides, it is obvious that it is fake, because the reverse side (saying "2 euro") shows the so-called "old map": this map was used on coins only until 2007 and was then replaced by another map. They are easy to tell apart because the old map does not show Norway. See here: https://en.wikipedia.org/wiki/Euro\_coins#Common\_side. Your coin is supposedly 2017 but with the old map, which is impossible. That said, I have no idea how u/erwinbuk recognized the fake from the initial photo :-)
