<p>[QUOTE=&quot;zumbly, post: 3004334, member: 57495&quot;]Nice!&nbsp; I haven&#039;t gotten any hits beyond two coins they found earlier provenances for when I first submitted four or five during their introductory offer.&nbsp; I&#039;d be surprised if the old CNG sales were recent additions to their catalogue archive; my understanding is that their software over time improves on its ability to match coins, and that the existing database of old submissions gets periodically run through the software.</p><p><br /></p><p>Other than a list of their catalogue archive, I wish it were known which auction companies they currently service in terms of finding old provenances for coins that are being offered for sale.&nbsp; I know that Künker uses them (sometimes you&#039;ll see auction lots in their online catalogs with links to provenances found by Ex-Nvmis) and so I certainly wouldn&#039;t submit to Ex-Nvmis any coin won in a recent Künker auction.[/QUOTE]</p><p><br /></p>
