<p>[QUOTE=&quot;Silverlock, post: 3702469, member: 98181&quot;]There have been fakes since the day after coins were invented. The challenge today is the millennials old race between counterfeiters and authenticators is tipping inexorably in the favor of the counterfeiters. This trend is by no means unique to ancient coins. Modern coin collectors have it far worse than we do. Every collecting area of man-made objects is having to deal with this trend. </p><p><br /></p><p>The reason for it is the technologies that improve the quality of fakes are cheaper, improving faster, and more widely available than the technologies that detect fakes made using those methods. Laser scanning, CAM for die creation, made-to-order metallurgy are cheap and readily available relative to neutron activation. </p><p><br /></p><p>My feeling is we are a decade or two away from exact 3D replicas of anything man-made. At which point authentication of objects themselves will no longer be feasible. Things like provenance chains and trust networks, which already dominate fields like art, will take precedence. Keep those receipts![/QUOTE]</p><p><br /></p>
