Diameter, weight, alignment and thickness are all fine; there is some lustre on the surfaces of the coin; while doing some of my own research I came across this: http://www.ebay.com/gds/Coin-Fake-Detection-Valid-Trade-Dollar-Types-/10000000016003602/g.html

and the Type 1 obverse with Type 2 reverse (my coin) is a valid combination for 1876 issues, which I have double checked by comparing the obverse's 'LIBERTY' scroll tips, and the reverse's left wing tip and eagle's neck feathers, which is making me feel better. I'd still like some other opinions, though, such as is that darkening around the figure of Liberty normal?

Bought for 190€ a year and a half ago, from a trustworthy dealer.
That darkening is normal, I mean, it's an artificially created patina and then removed, for example, by an ordinary rubber pencil. Ideas are left at the edges of the relief to better stand out. It's a normal cosmetic treatment to make the coin look better.
I like the details. I don't particularly like the rims and denticles. Unsure.
positive
- the details are very good.
- the color looks ok
- weight and dimensions are ok
- you bought it from a trustworthy seller

negative
- I agree on the denticles

Did you try some silver tests?
(ping, neodymium, ice, density....)
Non est totum quod splendet ut aurum
Rijkdom bestaat niet uit het hebben van veel bezittingen, maar in het hebben van weinig behoeften
My Thoughts.

Denticles dont bother me too much.

The darkening around high points definitely due to "erasing" of dark toning and the eraser was too large to get into the details. But this does not take away from authenticity of coin.

There are some other minor issues that may just be nonsense and just because of wear. Is anyone else out there questioning the edge/rim. Thats the only part that seems odd to me. Maybe its just the angle of photos.

Good luck,
Aaron

Yes, it's the rim that got me looking at the denticles more closely. I always pay more attention to the rims and denticles than the details, as the details tend to be counterfeited well on good counterfeits, but if the host coin had any issues it almost always transfers to the rim. I also wondered about the photography angle, so looked more closely at the denticles due to that. Hence my verdict of 'unsure'

For the others: The trade dollars were extremely well made and went through extraordinary quality control. Rims and denticles on them tend to almost always be completely uniform.
Thanks everyone for their input!

Regarding the rims, I think angle definitely plays a part since I take my pictures on a sloping surface with a light directly overhead, which is testament to my not stellar photography skills. Keeping everything in mind I'm pretty satisfied with my coin; everything seems to be OK.
