<p>[QUOTE=&quot;DonnaML, post: 4893192, member: 110350&quot;]I hope you realize that in posting the document I was sent I wasn&#039;t suggesting that the &quot;Certificat de Garantie&quot; for my coin has any independent value except as documentation of my coin&#039;s provenance back to 1975, which of course has some value when taken together with the coin itself.&nbsp; I wouldn&#039;t attempt to use it as proof of authenticity, but I don&#039;t think there&#039;s any question as to my coin&#039;s authenticity in the first place.</p><p><br /></p><p>As far as the value such a certificate might have had in 1975 is concerned, I think you may be going too far in suggesting that it was worthless. In the first place, these certificates -- complete with thread and wax seal! -- obviously enabled this dealer to sell its coins for higher prices than they would have sold for without them, so in the sense of market value alone they were obviously worth something at the time. In terms of whether they would been accepted back then as evidence of authenticity, I see nothing wrong with using &quot;agreed experts&quot; outside of Paris if they were known experts, even assuming that the dealer was the one who suggested them.&nbsp; Nobody has successfully identified the Dr. Cahn of Basel named on my certificate, but as for the certificate posted by [USER=75937]@Roman Collector[/USER] naming Xavier Calico of Barcelona and Hans Schulman of New York as experts, surely you&#039;ve heard of the famous Calico* firm of numismatists in Barcelona?&nbsp; See these excerpts at the Newman Numismatic Portal from Coin World articles published in 1979 and 1983 (one of them written by Hans Schulman himself):</p><p><br /></p><p><font size="3"><b><a href="https://nnp.wustl.edu/library/book/549521?page=79" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://nnp.wustl.edu/library/book/549521?page=79" rel="nofollow">Coin World [11/07/1979] (pg. 80)</a></b></font></p><p>11/7/1979</p><p><br /></p><p>COIN WORLD Wednesday November 7 1979 Page 80 Sons follow in dealer dad s footsteps By Hans M F Schulman Ithough Javier calico passed away 27 years ago it seems as if he is still alive His sons Xavier and Fernando kept their father s office just the way it was when he left His desk with the feather pen his closet with all the contracts and documents he signed everything as if he is still around His sons who are among numisma tists belonging to the most famous honor their father who really established the famous . . . .</p><p><br /></p><p><b><font size="3"><a href="https://nnp.wustl.edu/library/book/551054?page=2" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://nnp.wustl.edu/library/book/551054?page=2" rel="nofollow">Coin World [01/19/1983] (pg. 3)</a></font></b></p><p>1/19/1983</p><p><br /></p><p>COIN WORLD Wednesday January 19 1983 I The many faces of Xavier calico over the years in Barcelona Collectors mourn Madrid Basel Paris Bern Los Angeles and New York City F Xavier Calico Numismatists around the world are mourn ing the death on Jan 1 of numismatist Xavier Calico Barcelona Spain He was a victim of cancer Services for Mr Calico were held in Bar celona on Jan 2 He is survived by his widow a brother and two nephews partners in the famous . . . .</p><p><br /></p><p>(See <a href="https://nnp.wustl.edu/library/searchwithterms?searchterm=calico" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://nnp.wustl.edu/library/searchwithterms?searchterm=calico" rel="nofollow">https://nnp.wustl.edu/library/searchwithterms?searchterm=calico</a>.)</p><p><br /></p><p><br /></p><p>Hans Schulman was also a very well-known dealer in his time; see the articles at <a href="https://www.coinbooks.org/esylum_v08n25a17.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.coinbooks.org/esylum_v08n25a17.html" rel="nofollow">https://www.coinbooks.org/esylum_v08n25a17.html</a> (entitled &quot;Remembrances of Hans M.F.
