I just joined yesterday and the FAQ didn't really answer my dilemma.
It says that if it's the same coin but different material to create a different page and / or base it on the KM number. But what about a coin with the same material but different coloring issued from the mint and the coin is too new to have a KM?
I only have one of the coins, but I put all of the them in the same page... I figured that it would also help someone who is considering it as a series. If this was incorrect, just let me know and I will fix it and create a new page for all of them.
