<p>[QUOTE=&quot;Barfly, post: 1805515, member: 57721&quot;]Hi everyone,</p><p><br /></p><p>Long time lurker, first time poster. I&#039;ve been coin roll hunting for about a year now. I heard an interview with a guy in San Diego who apparently did it on an industrial scale and he got a visit from the US Marshals. I thought, cool, maybe I could get a visit from the US Marshals if I start doing this (haha), so that&#039;s how it all started. </p><p><br /></p><p>Anyway, last week, I found a 1967 half at the end of a roll and this thing is decidedly NOT made out of silver. The edge was indistinguishable from every other clad and it doesn&#039;t ring right. I would have thrown it in the discard bucket, except the roll fell over in my hand and I saw the date. It sort of reached up and smacked me that something wasn&#039;t right about this coin. </p><p><br /></p><p>Here is a web address of a drop box folder with some high resolution photos of the coin as well as some digital microscope images... (about 1.44 Gigs worth)</p><p><br /></p><p><a href="https://www.dropbox.com/sh/iyax7hmvgqzg35q/hQ4khRMaPD" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.dropbox.com/sh/iyax7hmvgqzg35q/hQ4khRMaPD" rel="nofollow">https://www.dropbox.com/sh/iyax7hmvgqzg35q/hQ4khRMaPD</a></p><p><br /></p><p>Please feel free to zoom in and scrutinize these to your heart&#039;s content. </p><p><br /></p><p>Here is a part of an e-mail I sent about the photos:</p><p><br /></p><p>&quot;</p><p>About the photos… There are 72 high resolution pictures and 22 pictures that were made with a digital microscope. The camera used was a Nikon D800 with a Nikon AF-S Micro Nikor 105 mm 1:2.8 GED lens. The desktop digital microscope is a generic off the shelf model and no manufacturer labels were on it. The magnification was 800x. The high resolution photos range from 12 to 40 Megabytes each and the microscope pictures are around 250K each.</p><p><br /></p><p>For the sake of comparison, the coin was photographed with a generic 1972 half (the test shot is of the 1972 half) and a 40% 1967 half. The coin in question is pictured individually and together with both the comparison coins and side by side with each comparison coin. There are front and back photos, and edge on photos. The edge-on photos were taken in groups of four rotating the coins 90 degrees at a time, so the entire rim could be studied. There are also some pictures in which all three coins were subjected to the tissue test. Two strobes were used in the photos. In varying pictures, the strobes are at different positions so that different details can be seen.</p><p><br /></p><p>My friend and I also measured the coin with a micrometer. It is within 1/10th of one mm of each of the others in both diameter and thickness.</p><p><br /></p><p>On weight: On a balance scale, the coin is lighter than the 40% silver specimen and heavier than the clad specimen. This morning at Collectors Coin Shop in Houston, their digital scale (which measures in tenth grams) read the following:</p><p><br /></p><p>40% Silver specimen – 11.8 Grams</p><p>Coin in question – 11.5 Grams</p><p>Clad specimen – 11.2 Grams</p><p><br /></p><p>This confirms what the balance scale showed. Obviously, the scale at the coin shop is somewhat out of calibration.&quot;</p><p><br /></p><p>I&#039;m hoping someone here can help me figure this one out. To the best of my knowledge, there were no clad half dollars produced before 1971. Yet, this one from 1967 is obviously not made out of silver. </p><p><br /></p><p>Is there anyone out there who might be able to help me on this one?&nbsp; I&#039;m out of my league at this point.[/QUOTE]</p><p><br /></p>
