I noticed the stress marks, which is a good sign, but you sometimes see them on forgeries.
Just for info, here's a coin that went for over CAD $300 a few months back. I had doubts about its authenticity, and one of the points that was made by one of our Numista specialists is the lack of stress lines.
As for the thickness, it's good to know that this is normal. I guess I never saw a picture of the edge of such coins before.
But the general appearance bothers me. It's not just cleaned; it's been polished, even on the edge.
