<p>[QUOTE=&quot;jgenn, post: 2962780, member: 78525&quot;]Thanks, AussieCollector, for presenting your 8 reales in a way that highlights the typical range of diagnostics that one should be aware of.&nbsp; Too many collectors only show pictures of the coin faces and expect a useful answer.</p><p><br /></p><p>The weight is reasonable.&nbsp; The specific gravity might be within range -- it is not easy to get very accurate results without a highly accurate scale and I don&#039;t know your margin of error.&nbsp; If I remember correctly, a 90/10 alloy of silver/copper should be 10.31.</p><p><br /></p><p>I don&#039;t see any obvious issues with the obverse and reverse designs.&nbsp; It looks like normal adjustment marks across Fernando&#039;s face.&nbsp; To bad about the &#039;X&#039; in the field near his chin, though. </p><p><br /></p><p>The edge design looks correct and the overlaps appear in the correct orientation to each other however the length of the overlaps do not appear to match, I can see one segment overlap in the first edge picture and three in the second.&nbsp; The parallel die mill would cause the length of overlap to match exactly.&nbsp; </p><p><br /></p><p>I think I can see evidence that the obverse/reverse was struck after the edge was milled.&nbsp; Evidence to the contrary would indicate a counterfeit.</p><p><br /></p><p>I have a concern about the overlap length -- perhaps it&#039;s correct and just not visible from the photograph.&nbsp; The specific gravity is slightly low and might provide the necessary margin for a counterfeit to be profitable.&nbsp; On the whole, I would guess genuine but it could be a well made counterfeit.&nbsp; Any third party grading service, however, would call this genuine -- they focus more on grading than a determination of authenticity.</p><p><br /></p><p>Get a copy of &quot;Counterfeit Portrait Eight-Reales: The Un-Real Reales&quot; by Gurney, Nichols and Lorenzo for even more diagnostics to look for as well as an explanation on why the demand for 8 reales in China, above other silver trade dollars, caused a proliferation of 8 reales counterfeits.[/QUOTE]</p><p><br /></p>
