I think those are really nice looking euro coins, especially as compared to some that I've already seen.
I would imagine a Euro seems like a lot of money to you, but if you can get your hands on a set, save it. Thirty years from now when you look at your collection they will seem very special to you. Also try to save a set of the coins that you have been using.
Any of those coins would be good coins for trading if you can manage it.
Take care!
