I agree the card looks real and probably a mistake. If you do a quick check going forward and backwards you can sometimes get an indication if the cards all came in with one submission (eg. a run of 1969s in this case). There appears to be a block of about 15-20 cards in a row "not found in database". I'm not sure if they leave empty certs for future use or what purpose skipping numbers would provide; but it's possible it's an inputting error....
If you send it in as a review and the case hasn't been tampered with; they will need to address it (I would think they would just crack/regrade with new cert).
Good luck!! Give us a follow up when you find out. Thanks.
