1. If you submit a card to PSA or SGC and they do give you a bump up (or down), do they assign an entirely new registration number to the card?

2. If they do change the grade, I assume they modify their registry to delete one card at the changed grade and add another at the new grade. Are they pretty good about doing this?

3. If you submit a card from another grader and they brake it open and regrade it, is there any communication to the other grading company to delete a graded card from their registry? Guessing no.

4. Can you tell anything from registration numbers about how recently a card was graded? Is their some code to crack for any of the registries?
