Hawaii coin [решено]

Any comment on this coin. Is it authentic?

When you post pictures of coins cut away everything around the coin, then your image of the coin itself could be big and detailed enough. Without a detailed image there is little chance of getting a correct answer.

Your pictures are too blurry to be certain, but I don't like the look of the dentils, which should be sharp and consistently the same all around the coin. What does it weigh?

It's 6.1 g

The pictures provided for coin's identification should look more or less like this. When images are sharp and detailed it is easier to make a judgement.

This coin was sold by Heritage Auctions and it is original.

Judging by the blurry images we have in the first post and the low weight of 6,1 g, I'd say it's a fake.
