Hello,
It makes no sense, to count this coin for 2017.

The year on the coin is 2018.
It is just issued in December 2017. Like the 2018 2€ coin "Republik of Austria".

I think, we should change the year from 2017 in 2018.
If not, we should change the year of the 2€ coin 2018 in 2017 too and all the "New Year"-coins we should date one year back. But this would be nonsense. So please, change anybody the year of the 2018 new year coin in 2018.
