Morgan authenticity

Hi
I am a UK based collectors generally buying British coins, but I am venturing into starting a US coin type collection.
I bought an 1885 Morgan Dollar on ebay from a UK seller recently. On initial inspection I was really pleased with the coin. But I have been learning about morgans and the problem with fakes.
I have put it on the electronic food scales in the kitchen it said 26g. I have tried a very strong magnet, there is no attraction at all but when I move the magnet over it I feel ever so subtlely some kind of interference in the movement of the magnet. I have also learnt there are fakes which are silver ans weigh correctly.
Please could I ask your seasoned eyes to look over my pictures? On the face there is what looks like slight rusting or oxidation that you can see in some light or angles but which then disappears at other angles.
Thanks in advance,
A

PS: lots of US coinage in Europe not available to us stateside collectors. Should be good pick'ns.
Here is a way to test for silver (coins at 3:00 mark):
Looks ok and very nice strike for a O mint to bad about the dark area on the face,

Looks fine to me.
That resistance is due to Eddy current.

Genuine. Also looks like a Vam-11. Which probably doesn't matter to you unless you are planning to collect die varieties, but it may confirm authenticity. I will add a link at the bottom of the page. If you have a strong magnifier, check for the vertical die polishing line top left outside the ear that is shown in the LVA plate photo. The other pics will probably confirm the other areas as well! Congrats on your find!
