Today at a gun show a vendor had a 1/2 oz gold American Eagle for sale for $10 over melt (half of the ounce going price). I took my handy dandy cheap digital scale with me and had already weighed a silver one ounce eagle and came up exactly 1.00 troy ounce.
When we put his 1/2 oz gold eagle on it, it repeatedly weighed 0.55 ozt. I was concerned enough that I didn't pull the string on a deal. I don't have one at home to test so am wondering if there is a discrepancy in these coins.
Any help appreciated.
