<p>[QUOTE="GDJMSP, post: 1796192, member: 112"]Yes, the high points of a toned AU or XF are usually lighter in color than the rest of the coin. But that is not because when the toning is worn off it reveals the luster underneath the toning. There can be no luster on the points with wear. Even light wear destroys the luster. The only reason the high points are lighter in color is because the toning is worn away revealing the lighter colored metal under it.</p><p> </p><p><br /></p><p> </p><p> </p><p>They not only could have some luster left, they <u>should</u> have some luster left. If they do not, then there is a good chance the coin is not really XF. Both the ANA and PCGS grading standards use this criteria. The luster requirement really splits between XF45 and XF40 - 45 requires it, 40 does not.
