<p>[QUOTE=&quot;calcol, post: 5474292, member: 77639&quot;]At some point, a standardized, public laser scan may be developed that has the resolution to identify individual coins.&nbsp; The scanner may be cheap enough (a few $100, maybe less) that most dealers, advanced collectors, clubs, etc. can afford one.&nbsp; Scanners would be connected to the internet, and the database would be maintained centrally, perhaps by the ANA or a new NPO.&nbsp; Certification numbers, if known, would entered with the scan, and each coin would have a unique scan ID. </p><p><br /></p><p>If a coin is scanned and has been scanned before, the user would be able to see the existing scan ID.&nbsp; If a scan ID is entered on the maintenance website, any TPG certification numbers in the database would come back.&nbsp; If a TPG certification number is entered, the scan ID and any other TPG cert. nos. would come back.&nbsp; The database could also be used for auction history tracing and recovering lost or stolen coins.&nbsp; At some point when TPG population numbers become really ridiculous, even the TPGs may support the idea.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
