Also for Italy we have a problem with the 1, 2 & 5 eurocents designs and their KM#.
Up to and included 2016 the 2 cents coin has the original design with the KM#211, but in 2017 the design has changed as you can see above, but since KM doesn't attribute KM# any longer, Numista is stuck. I suggest to use the original KM# and the applying the rules for small design changes to create the NC#211.1 (NC = Numista Coin #) for the new coin.
I'll now have a look at the 5 cent coins.
What do you think, should we take the numbering into our own hands, or just let everything be as is?
