I had a 10 book submission received on Oct 29th, 2021. I checked on it a week later and it said "shipping". I thought I did something wrong and they were sending the books back to me, as I have never had CGC act so quickly. But no, they were done and I had the 10 books in hand on Nov 9th, 2021. I will say that all 10 books were the same book and got the same grade and page color. SO not sure how long they took on the books or if they were "cookie cuttered", meaning looked at one and the rest looked the same so they gave it all the same grade, slabbed it and sent it out.
