Bought this nugget a while ago from a reputable source and from my research and understanding it appears to be a platinum nugget but I would like a second opinion.

Location: Kondyer Massif (alleged), Khabarovsk (confirmed/certain)

The mineral is not magnetic to neodymium or ferrite magnets of high strength and the nugget feels quite dense in the hand and weighs 32.5 grams.

Nugget has visual chromite spinel inclusions and limonite inclusions.

I recently acquired this beauty of a coin and I’m curious if the green spot in the red circled area is toning or verdigris?

I just wanted to make a post and share my first ever English coin and where my English coin collection started from.

My first ever English coin was a 1687 Crown (2nd Bust) of King James II who was the last Catholic King of England. It is a coin I’m very honored and proud to have in my collection as it is a rarer coin from a rarer monarch to have and it is in quite a high grade given the history and circumstances of this particular monarch.

I made a post about this coin a few times before but I wanted to get another opinion on authenticity and where to go from there and whether it would be possible to get my coin published in a journal or paper.

I acquired this coin from Heritage Auctions and it has been graded by NGC as AU-55. However, I talked to a dealer specifically specializing in Russian coins and he said he is completely unaware of Russian imperial platinum coinage having overdates. Which is why I came here to see what the consensus is. I understand I bought it from a reputable auction house and NGC (reputable grading company) has already certified it but I want to be sure that what I have is a genuine specimen and not a fake. Any tips and advice is appreciated!
