<p>[QUOTE=&quot;dougsmit, post: 2342720, member: 19463&quot;]On Carthago point 4:&nbsp; I wonder how the technology could handle coins that have been altered or just cleaned.&nbsp; I bought the coin below in 1991.&nbsp; As was then part of my technique, I went through old catalogs in my collection and found a match to the type in a previous Empire catalog but that coin had fewer marks and pits.&nbsp; Denis Kroh replied that he could not tell me the name but the buyer of the coin was &#039;famous&#039; for &#039;improving&#039; his coins with additional cleaning and he thought my coin was the same specimen that appeared in his earlier sale (rather than a fake made from it or a mother to both).&nbsp; Many coins have had &#039;experiences&#039; we might prefer they had not.&nbsp; A coin like mine may not have qualified for illustration before the 90&#039;s so the likelihood of tracing it back beyond the Empire sale would be slim.&nbsp; The question is whether a computer would recognize the old and &#039;improved&#039; version as the same.&nbsp; I should add I paid less than 1/4 of the Empire realization so &#039;improvement&#039; was not a good idea in this case.</p><p>[ATTACH=full]476195[/ATTACH][/QUOTE]</p><p><br /></p>
