I’m not sure about avoir dupois ounces vs. troy ounces, but I
came up with $106, based on 27g per ounce. I’m not sure if
that’s the correct number of g/oz. for precious metals. But
anyway, if it’s scrap, old chains, etc., I don’t know if I would
give the spot price for it.
=((spot price * (# grams/27)) * karat / 24 …Again, not sure
if 27g per ounce is correct.
Food for thought,
