<p>[QUOTE="Get Real, post: 2510975, member: 81585"]I do agree that on the reverse it looks cut although "Cut" is not the term that I would use. It has taken some time to review this coin and come up with a way to explain why I don't think that it is PSD so bear with me. First I would like to say that this coin has been around for 50 years so I am not saying that it hasn't had some abuse over the years. My point is to the root of the damage and when it may have occurred.</p><p><br /></p><p>First, Look at the picture below. It is a close up of the Reverse showing that the two surfaces are in fact perpendicular to each other. The walls show hairline striations perpendicular to the face which is typical of being sheared not cut. These same striations appear when any metal has been punched in a press, the first 50%-80% (depending on composition) of depth being clean and the remaining 20%-50% being rough from breaking. This coin does reflect the same features as I just described and although not impossible to do in someone's home its probably not likely.</p><p><br /></p><p>[ATTACH=full]534014[/ATTACH]</p><p> </p><p>This next picture is to give a visual of both sides of the coin and the orientation of the damage. I don't have the tools to do an overlay so this will have to do, sorry! It also shows (In Red) the curvature of the die strike hasn't been disrupted as well as some missing material (Shaded in red) that would be near about impossible to do without disrupting the rim. The other comments I will explain in another picture.</p><p><br /></p><p>[ATTACH=full]534020[/ATTACH]</p><p><br /></p><p> This next picture is the root of most of my non PSD suspicions. If you look at the edges of the damage on both the Obverse and Reverse, they show the metal pushed out beyond the missing material creating a ledge.
