<p>[QUOTE="Valentinian, post: 4105064, member: 44316"]The folles had a small, but significant amount of silver in the alloy and on the surface. Because silver was worth, by weight, 100 times as much as copper, even 1% silver would double the intrinsic value (making a 10-gram coin as valuable as a 20-gram pure copper coin). There is some evidence that eastern folles had higher silver content than others. Maybe there are articles on this. I personally had a follis of mine analyzed at the Ashmolean Museum in Oxford. It was a 9.43-gram "XXI" Diocletian follis from Alexandria. The interior tested as 3.96% silver, not counting surface silvering, which adds about a percent. </p><p><br /></p><p>If that one coin were representative (a sample size of one is too small!), then the intrinsic value of a XXI follis would have the intrinsic value of a 50-gram pure copper coin.[/QUOTE]</p><p><br /></p>
