From the CAC - FAQ section:
Are the serial numbers of PCGS or NGC coins submitted to CAC for verification recorded? If so, are coins automatically rejected by CAC that have previously been submitted but were not stickered?
The serial numbers of all PCGS and NGC coins that are submitted to CAC are recorded at the time they are entered into the CAC system.
All PCGS or NGC coins that are submitted to CAC are reviewed for CAC verification whether they have previously been submitted to CAC or not. Occasionally a coin that has previously been rejected for CAC verification is reconsidered by CAC and stickered.
