<p>[QUOTE="Severus Alexander, post: 7656582, member: 84744"]You're right about the decline in fineness. Here's a chart:</p><p>[ATTACH=full]1316345[/ATTACH] </p><p><br /></p><p>So why do the coins from emperors low on this list look so nice and pure? My understanding (which I'm getting from Warren Esty) is that it's a metallurgical thing. Coins with low fineness will typically have enriched (80%+) surface silver content because of striking. Silver is more malleable and so it moves more easily to the surface when the coin is struck; the copper tends to stay in the core of the coin. Cutting one open will demonstrate this. I don't advise it though![/QUOTE]</p><p><br /></p>
