<p>[QUOTE=&quot;LMHESS, post: 2185970, member: 75003&quot;]I collect many different types of collectibles, most smaller in size from antiquities to antiques.&nbsp; I recently started collecting coins, so I have to rely heavily on reputable dealers, and the authentication services.&nbsp; I work in the dental field and can tell you that technology with the correct equipment can duplicate every aspect of an authentic coin down to the smallest nick, scratch, wear or even a die crack using a laser scanner and then a laser printer that makes an exact duplicate of the original coin or object out of plastic or porcelain. (in our field)&nbsp; There is an ebay member jmarin that duplicates original 18th and 19th century South American crosses and medals and sells the duplicates honestly as duplicates.&nbsp; Duplication seems to be pretty much mastered.&nbsp; It almost looks to me that identifying an counterfeit coin is going to come down to weight, metal chemistry, color and patina.&nbsp; I do see that the authentication services offer restoration services.&nbsp; I really think that this is good since many applied patinas are usually easily removed.[/QUOTE]</p><p><br /></p>
