You've also got to keep in mind technically this coin could be copied by a skilled mint, and a pretty good copy could be made. Not being a funded coin with holo's/addresses and what not obviously makes that easier. It also isn't going to be easily identifyable like a US Fiat coin would be to a trained eye, for ex. No one is trolling though, just a very highly priced item and explaining why it's perhaps overpriced.
Actually, I think it would quite easy to spot a fake. Every cryptonic coin has a unique code engraved on the rim that you can input into the site for verification & will tell you if it's authentic or not. That adds a level of complexity to counterfeiting them, as these codes are not public - afaik only cryptonic21 has full access to them all. I will actually ask him to chime in here on this, as we have discussed it briefly in the past, but yes, in general, of course someone could easily counterfeit anything with the right tools and skills, IMO.
I guess this coin is original with 99,9% probability. It looks exactly as it should and the ID is correct.
As for the price it can be determined only by the seller and a buyer.
