There have been rumors about a common €2 commemorative coin, to be issued in 2015, with the theme "30th Anniversary of the European Flag". Actually the flag is older, but in 1985 it was adopted as an EU symbol.
When our member Frizio showed us his idea for such a coin (
see here), I initially thought that there won't be such a piece. Well, except there are serious thoughts about it ... Currently we do not have an official decision yet, but that may change.
As a collector I am not really fond of the idea. Yes, if the euro area was able to agree to a truly common issue, that would be interesting. However, if this was one of those joint issues - with 19 almost identical designs - my desire to get the pieces would be close to zero.
