<p>[QUOTE=&quot;Colonialjohn, post: 2488865, member: 57741&quot;]Personally I think the coin is legitimate since to me this does not look like an electrotype seal. Further since the weight is spot on this favors its regal status. I have a new book coming out in a few months via Amazon Books on counterfeits. Much information backed up with XRF data and in my book I address these Crowns or at least show a contemporary counterfeit of this period and discuss its diagnostics in my World Chapter which runs from 1500-1800 for several countries primarily England, France and Spain. An electrotype with a rim to rim die break and a proper regal weight. I don&#039;t think so ... the edge looks like a Castaing Edge slippage outcome (i.e., not really an error per se as slippage of edge devices occurs occasionally and has no real premium IMO from these poor pictures).</p><p>England experimented briefly with milled coinage, but it wasn&#039;t until <a href="https://en.wikipedia.org/wiki/Peter_Blondeau" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Peter_Blondeau" rel="nofollow">Peter Blondeau</a> brought his method of minting coins there in the mid-seventeenth century that such coinage began in earnest in that country. Blondeau also invented a different method of marking the edge, which was, according to him, faster and less costly than the method pioneered by Olivier. Though Blondeau&#039;s exact method was secretive, numismatists have asserted that it likely resembled the later device invented by <a href="https://en.wikipedia.org/wiki/Jean_Castaing" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Jean_Castaing" rel="nofollow">Jean Castaing</a>. Castaing&#039;s machine marked the edges by means of two steel rulers, which, when a coinage blank was forced between them, imprinted legends or designs on its edge. Castaing&#039;s device found favor in France, and it was eventually adopted in other nations, including Britain and the United States, but it was eventually phased out by mechanized minting techniques. Although I did not confirm if this particular issue was the result of this anti-counterfeiting technique in KM. At work ... its regal to me unless further data is revealed. THis strong die break in terms of its sharpness also rules out cast IMO. </p><p><br /></p><p>John Lorenzo</p><p>United States[/QUOTE]</p><p><br /></p>
