Chinese Fat Man Dollar -- Authentic?

@Spence, thanks for that link. I had looked at some other Fat Man threads, but I didn't see that one. I just counted the denticles, and there are 101 wide denticles and 100 thin denticles on the obverse, same as the coin in that thread. My eyes tired out before I got to the reverse. I assume it still might be counterfeit, but it looks good to me, too. Thanks everyone for your opinions!

I don't think you need to count dentils here. This is a legit coin with what appears to be an unusually dark patina. Perhaps it is just the image.

This is a nice XF-AU specimen.

I had posted this coin a few years ago, and I finally decided to send it in last month for authentication and encapsulation, mainly because it's an heirloom piece and I wanted to make sure it was genuine. I was surprised at the grade--shows how little I know about grading foreign coins...

Very nice result!
It's great to have a questioned coin come back as it did!
I have so many look-a-likes sometimes it's hard for me to offer an earlier opinion on a photo alone.
I can only think of a couple or very few look-a-likes I've had over the years that ended up being genuine.

Thanks everyone. I'm obviously pleased with the result. @Hondo, it was passed down by my father, and I believe he had it for many years. But I don't have any history beyond that, so I guess the family history will start with him.

Nah, neither of you are crazy... This is a prime example of NGC grading too generously - particularly in higher circ grades.

That said, this is a nice deeply toned original piece - a slight circ cameo thing going on - with a lot of meat left.

Grading has never been much concern for my collecting.
I did read somewhere, maybe in Krause, that grading for world coins differs from how American coins are graded.
Not sure how these various grading companies deal with that.
If I ever submitted a coin, I'd do it just to confirm or deny authenticity, but I wouldn't give a hoot about some person's subjective opinion of a grade.
Wouldn't surprise me even if some of these people could even get an authentic coin to be non-genuine or perhaps a non-genuine coin to be authentic.
