^ Correct. You can't really compare the two creeds because not only were the bags made in different factories in different months (one was made in April 2006 and the other was made in Nov. 2006), but the L0668 one is from a different color tote.
There were genuine Sig Stripe Totes that had creeds starting with the D06K serial number prefix. The counterfeiters chose to use the D06K code as the "template" for their fake Sig Stripe Totes, probably because that was when style first came out and they copied the serial number from what was in production at the time. I've seen fakes of this style and there are always other details that are wrong. Looking at the pictures of the bag in the auction, I don't see these red flags. I still believe that the bag in the auction is real.
