Robert,

Yes, steel is harder than nickel silver which is (roughly) 2/3 copper. And inasmuch as you have already tracked down comparable examples for the thread starter, what I am interested in right now are the backsides, and the markings. So if you have any good images of that aspect, and of course any high resolution ones of the front not yet posted, I would be very appreciative.

Thanks, Fred
