The stack of ten weighs 125 grams. My scale doesn't do partial grams so I weighed them as a group. The edges look white to me. The
tissue test looks white for them — at left under the tissue is a known copper-nickel (business strike) BU half for comparison.
Ring test sounds like a Franklin. Not like the clink clonk (the proper scientific term, for any sticklers out there) of the clad half I compared them to. Only tested two for sound.
Any confidence that I can gain that these are silver, or reasons they might not be silver, would be helpful.
I don't think I've ever owned a modern proof silver coin so I feel kind of unsure about the whole thing.
The pictures of the edges are the same halves in the same order, just facing the light at two different angles.
