<p>[QUOTE=&quot;iPen, post: 2600194, member: 69760&quot;]I&#039;ve always thought of this, too, with respect to 3D laser mapping a surface of a coin. I didn&#039;t know that someone(s) already had the patent rights for laser mapping, but I&#039;m not surprised at all.</p><p><br /></p><p>Anyway, the issue I&#039;ve always wondered is what the baseline coin would be to which all other coins would be graded. One can manually grade the most flawless coin and use that as the basis for the mapping, but that would be begging the question - is the baseline coin perfect and how would we know definitively? And, what would happen if no &quot;perfect&quot; coin exists, especially for pre-modern coins - do they simply extrapolate some sort of simulated image? But that would be controversial, to say the least. Alternatively, one could use the original dies and invert the design, but I don&#039;t see the US Mint allowing anyone near their in-service dies, let alone permitting its scan every single year for each new release. Not to mention, every other country&#039;s Mint would have to allow it, too...[/QUOTE]</p><p><br /></p>
