<p>[QUOTE=&quot;Lolli, post: 4547647, member: 96900&quot;]I add some links to coins with rised lines (die breaks in ancient dies/matrixes will occur as rised lines with higher relief on coins). And on such rised lines from die/matrix breaks patina can grow and patina is not always growing everywhere equally and even. (As possible explanation for rised line which is cycled black on picture, but there can be of course many different explanations all I want to show is that such lines can occur on authentic coins, too and are not necessarily an evidence for a coin to be fake.</p><p><br /></p><p>Examples for die Breaks, showing that they will occur as rised lines:</p><p><br /></p><p>Through eye</p><p><br /></p><p><a href="https://www.acsearch.info/search.html?id=1495631" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.acsearch.info/search.html?id=1495631" rel="nofollow">https://www.acsearch.info/search.html?id=1495631</a></p><p><br /></p><p>Through head</p><p><br /></p><p><a href="https://www.acsearch.info/search.html?id=351324" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.acsearch.info/search.html?id=351324" rel="nofollow">https://www.acsearch.info/search.html?id=351324</a></p><p><br /></p><p><font size="4"><b><a href="https://www.cointalk.com/members/aussiecollector.81093/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/members/aussiecollector.81093/">AussieCollector</a></b></font> &quot;But... what about the sanding of the edges?&quot;</p><p><br /></p><p>I have authentic sestertii, that have such &quot;sanding&quot; removed patina on 1 or two spost on edge too, not sure why they are there but my coins are 100% authentic with a 100% authentic patina and the patina pretty much everywhere intact on them.</p><p>File marks on the whole edge to remove casting seam and sprue would be a serious problem.</p><p>But on the Nerva the patina on the edge seems to be intact except on two spots and I can not see there file marks or traces of casting sprue edge.</p><p>If you produce a cast fake you generally remove the seam and sprue first and then you apply an artificial patina. </p><p><br /></p><p>Imho it is not possible to do a reliable authentication based on this pictures, it could be authentic or fake so much better pictures would be required or an examination by one or better more REAL experts in hand.</p><p><br /></p><p>I am not sure if it is so good and fair to mention and attacking the seller although it is not proven that the coin is actually fake and even if the coin would be fake, everyone makes mistakes and the seller does not seem to sell knowing+intentionally fakes and even if the coin would be fake it would be a honest mistake and the seller is even offering a refund although it is not proven that the coin must be fake.</p><p>I do not understand what the seller did wrong.</p><p><br /></p><p>And if a real expert like Curtis (working as expert for HJB) says that the coin looks ok for him, then I would at least overthink my opinion because the chance that Curtis is wrong is much lower than the chance, that you are wrong.</p><p><br /></p><p>&quot;<font size="4"><b><a href="https://www.cointalk.com/members/curtislclay.89514/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/members/curtislclay.89514/">curtislclay&quot; &quot;Looks authentic to me, because of the sharpness of some of the details and of the pitting on the obverse.&quot;</a></b></font></p><p><br /></p><p><font size="4"><b>To accept only and appreciate opinions or arguments that support the own opinion is not good because then contrary opinions will be neglected although the other side is possibly right and has&nbsp; the better and more convincing arguments.</b></font>[/QUOTE]</p><p><br /></p>
