I have a question about 2 kune coin from Independent State of Croatia. It was made out of zinc and since the numista site for this coin states that "There are some reports about 2 Kune from 1941 minted in both nickel and copper with diameter of 20 millimetres. However, both of these are considered replicas.", how can one determine if the coin is copper, nickel or zinc? I have no trouble identifying copper but nickel and zinc could be problematic. This is not an expensive coin but I don't want to get a fake one even for 1€ or $1.
Another question, I've read a post somewhere that this coin was actually minted in 1944 even though the year on the coin is 1941. Is that true?

Zinc is considerably lighter than nickel and copper. Measurement of density can easily distinguish zinc from the other two. Also, according to the comment the nickel and copper ones are 20 mm diameter vs. 18.8 mm for the zinc one. However, the easiest way to check nickel vs. zinc is with a magnet. Nickel is highly magnetic.
Zinc usually adopts a grey hue with age. There was only ever one circulation strike and that was in zinc, the other metals are either replicas or patterns. Much much rarer is the elusive one kuna
