Abstract: A method of certifying the condition of a collectible item, including establishing a unique identification number for the item; evaluating the item and determining a numeric grade for the overall condition of the item; entering the item identification number and the numeric grade in a worksheet; saving a read-only record copy of the worksheet in a registration database keyed to the identification number; generating no more than two identical labels with the identification number for the item; creating a separate registration certificate that displays the numeric grade for the overall condition and other identifying information for the item; applying one of the identical labels to the registration certificate; and applying the other one of the identical labels to the item or a container of it. The labels are secure ID Tags, being unalterable and tamper evident by destruction if removed. They form a security seal when affixed to a container.
