What is the NGC grading process?
When a submission is received by NGC, it is opened by trained staff under security cameras. Each coin is entered into NGC's proprietary tracking system and assigned a unique identification number with a barcode that is used to follow the coin throughout the NGC grading process. At this stage, the coins are separated from the submission paperwork so the NGC graders never know the submitter's identity, which ensures impartiality.
Coins are then transferred to the NGC grading room, where several professional graders carefully examine each coin. After grading, coins are encapsulated in NGC's EdgeView® Holder, the same holder that was extensively tested by the Smithsonian Institution and is currently used to protect more than 300 of that museum's greatest rarities.
After encapsulation, coins are returned to the NGC grading room for a final inspection. Images are then taken of the encapsulated coin for NGC's free online Verify NGC Certification tool, available at NGCcoin.com.
Finally, the coins are matched up to the original submission form and brought to NGC's shipping department. Every coin is individually counted and checked against the submission paperwork to make certain that no mistakes occurred. Coins are then securely packaged in a sturdy cardboard box that contains dividers so that the NGC holders do not come into contact with each other. The NGC-certified coins are now ready to be sent back to the submitter.
