https://en.numista.com/catalogue/pieces10560.html states the 2013 weighing 10 grams is magnetic (nickel plated steel)!
https://en.numista.com/catalogue/pieces57162.html states the 2013 weighing 8 grams is NOT magnetic (copper nickel)!
I have a 2013 weighing 8.03 grams, thus it is supposed to be the second coin, km18a, but surprise, surprise, it is MAGNETIC (steel), so it's either a km18b (doesn't exist yet!), or the Numista catalog is NOT correct


I have sent the data and images to KM already, so in some months time we might find it in Numismaster!
