Anyone recognize this triangylar mark on a large silver bar?

This bar weighs approximately 75 troy oz (5 lbs 2 ounces). The only markings are this triangle looking thing and what appears to be a serial number.

The bar isn't in my possession, but it seems to be silver. Any help would be greatly appreciated.

Correction: there are two bars shown in the picture. Each weighs approx 75 troy oz.

    That's an "A" over an "M" but I do not know who makes that.

    I thought it looked masonic at first glance, but I see that A and M.

    I met with the owner of the bars this evening. They aren't 90%, 92.5% or 99.9% silver. Based on the dimensions of the bars compared to their weight, it's about 65% as dense as .999 silver. No idea what metal it would be, as even a home pour silver/copper alloy bar would be more dense than whatever this was.

    The plot thickens. Could it be Tin with a specific gravity of 7.5?image

    Worry is the interest you pay on a debt you may not owe.

    Why not have it analyzed... can be done easily without damage.... Cheers, RickO

    We're looking into options now to have it analyzed. He has half a dozen of these bars, so it's worth looking into.



    It did ping decently well, though not like 90%+ pure silver.

    Why wouldn't someone mark it if it was?

    I'm guessing the bar had a paper label which has long since been lost or it came in a wooden box with several other similar bars for industrial use with the wooden box labeled. Tin is the main component of pewter.

    It was likely intended to be used shortly after receipt whatever it is.

    Possibly Antimony? THe density would be about right.

    Edited to add: the link does not work. Look up Antimony in wikipedia.

    And BTW, not every light-grey colored ingot in the world is silver.

    Or perhaps it could be zinc which is used to galvanize steel to prevent rust.
