This is exceptionally difficult for lower-grade/heavily-damaged coins in which the diagnostics can be greatly distorted. However, that much alone is not good enough for these fakes. The repeating marks need to be seen on multiple examples for it to be flagged as counterfeit. So you would need to scan every single coin to get a full profile. You would also need to be able to differentiate the strike characteristics of the counterfeit from damage like whizzing or smoothing.</p><p><br /></p><p>Then there is the problem of differentiating depressions from worn-down contact marks. Even under magnification, they look the same, hence the need for multiple examples.[/QUOTE]</p><p><br /></p>
