Quote from bill on May 13, 2013, 3:03 pmUnfortunately, there is no good way to tell the difference except through color. Jeff and I produced a color chart for the various finishes on the 1915 Panama Pacific International Exposition official medal. It was published in the August 2012 Numismatist and I think I have a link to the chart here on the discussion board. We will likely produce one for the 1904 medals, but that is a couple of years down the road. The weights should be the same and surface testing will likely not help as well.
It there a way to tell a HK-301 from an HK-303? By weight, chemical test?
