<p>[QUOTE=&quot;justafarmer, post: 7574391, member: 3926&quot;]Counterfeit detection for a coin struck from a pair of dies made from an authentic source coin has 3 levels of die markers subject to authentication.</p><p><br /></p><p>Level 1 are the die markers of the authentic die pair used for striking real coins. A real coin should possess all the of these die markers. A coin that does not exhibit all the die markers of an authentic coin would be a suspect counterfeit. As these would be die markers present on the source coin that were not transferred to the counterfeit dies.</p><p><br /></p><p>Level 2 are the elements unique only to the source coin which are transferred to the counterfeit dies. These markers would be common to the source coin and all counterfeit coins struck by the counterfeit dies but would not be exhibited by any other authentic coin except the source coin. Any coin, except the source coin, exhibiting these markers would be a suspect counterfeit.</p><p><br /></p><p>Level 3 are the counterfeit die markers. These are produced during the actual manufacture of the counterfeit die. These markers are unique to the counterfeit dies and will be common to all counterfeit coins struck by the counterfeit dies. These markers would not be exhibited by any authentic coin, including the source coin, because authentic coins were not struck by the counterfeit dies. Any coin exhibiting these markers would be a suspect counterfeit.</p><p><br /></p><p>While a counterfeiter can always produce new and better dies from a level 1 and level 2 marker aspect; level 3 is a different issue altogether. The newly counterfeit dies will contain their own set of unique markers created during their manufacture.[/QUOTE]</p><p><br /></p>
