SGC Grading Date? (Reholdering from old slab to new slab)

[bk400]

I reached out to SGC to ask about the grading date that appears on their card verification database. Apparently, that "grading date" could be either the date the card was actually inspected for a grade OR the date that the card was reholdered into a new slab. In addition, SGC assigns a new card certification number when a card is reholdered.

I appreciate that in an ideal world, the grading standards for a card slabbed 10 years ago are the same as those for a recently graded SGC card. This said, the implication seems to be that a card in a new SGC slab with a recent grading date might just be a recently reholdered card.

Any thoughts on this?

Well, SGC is one of the companies that won't automatically reholder cards into new holders without being regraded, if the cards were submitted under previous ownership groups. I have seen 2-3 threads complaining about it here in the past month.
Here is one of them:

I have seen quite a few reholdered cards that reflect their original grading date when looking them up? Did they say what variable(s) re in play that makes it go one way or the other

In my email correspondence with SGC, I specifically asked whether the date graded would be the date of the reholdering or the date of the original grading, and the response was that it would be the date of the reholdering.

I suppose that this could imply that every time an SGC card is reholdered, it is effectively re-graded. But not sure.
