<p>[QUOTE="desertgem, post: 644400, member: 15199"]Most Likely your uncle received it cleaned, as cleaning was an unfortunate, but common technique of collection and displaying many decades ago. As knowledge and techniques have changed, many collectors have ditched their cleaned coin on ebay, but many purchased a long time ago, and have retoned, are sent to TPGs and decisions are made there. I can't see through most of the toning on the obverse to tell cleaning marks, and I am not sure of the light spots ( base of cap, front of eyes) is actual color or if glare. If that disparity with color is on the coin, that is one indication. The reverse seems much more affected. I can see where the inner area of the lettering is cleaner( lighter) than the surrounding patina ( like the "C" in AMERICA), and other places where one would normally expect darker, it is lighter.</p><p><br /></p><p>That said, I could only say in my mind "suspected" if it didn't have the 3rd party designation by the photos. Much of such problems are only seen by tilting the coin in light and good magnification with resolution. Even if a person has the best resolving camera lens, shooting through common plastic reduces the lens to like a plastic magnifier (resolution wise). That is why if one wants accurate photos for later use, do it before having it slabbed. I wish I had figured this out before I sent off some of mine.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie9" alt=":eek:" unselectable="on" unselectable="on" /></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
