<p>[QUOTE="Conder101, post: 2795233, member: 66"]I never trust the edge. When new the 20%silver 80% copper core is almost the same color as the 80% silver 20% copper outer layers. If the edge doesn't get a lot of handling it won't darken that much and will tend to remain about the same color. If it does receive a lot of handling the center can darker quite a bit and start looking a lot like a coppernickel clad. Always use weight to tell 90% silver from 40%, and specific gravity, and sometimes the tissue test, to tell 40% from coppernickel (Weight is not conclusive on 40%/coppernickel)[/QUOTE]</p><p><br /></p>
