Judd 370 is a die trial using the same dies as the regular issue, but struck in copper instead of bronze.  Because of the similarity between copper and bronze alloys, metallurgical analysis is recommended.  Copper and bronze can be found in a variety of colors, some of which mimic each other, thus it is impossible to determine alloy by sight.
