I have a few NGC slabbed coins (mostly shipwreck certified) I purchased over the years. I want to submit them to NGC for regrading, upgrading their holders, and new labels. I also want to have their serial numbers updated to reflect the submission numbers I submitted them under and not retain their previous submitter's serial number. Basically, I want them to be under my serial number and not the previous owner's. Getting new holders and labels is easy, but is there a special request I can make to get updated serial numbers?
Thanks!
Robert
