Hi, Can anyone please help me identify authenticity of this coin? Weight is exactly 31.83g. If fake, what are the clues? It's not iron, I checked with a magnet, and seems otherwise very convincing but I can't confirm the source & I know there are quite well-made forgeries of this series. I don't have another confirmed coin to compare with. It would be much appreciated. Coinuniverse.
