<p>[QUOTE=&quot;SuperDave, post: 2267257, member: 1892&quot;]Here&#039;s what I suspect Physics-fan is considering: first, luster/brightness renders in a scanned image as dark, black if it&#039;s bright enough. This makes evaluating scans iffy because worn, dark areas on a coin can approach a similar shade, and you have to learn to interpret between the two.&nbsp; Your coin, in this set of scans, appears dark enough to worry about. A red flag is the similarity of finish between fields and devices as expressed by that darkness; it means both areas should have about the same finish in-hand, perhaps indicative of cleaning and evocative because the coin doesn&#039;t seem to show enough wear to have reached this point naturally.</p><p><br /></p><p>Another (important) point he may be considering is the halos around the stars and edge of the devices. Under any imaging system, those are an immediate red flag for cleaning.</p><p><br /></p><p>He was also wise enough to emphasize that it&#039;s not possible to form firm opinions from one set of images of a coin, of any quality. That caveat should be a universal stipulation in numismatics; those of us who do a lot of imaging (raises hand) naturally weave the thought into our workflow. And scans, from the viewpoint of a photographer, are actively trying to lie to me. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
