As mentioned, the only way to get them numbered sequentially is to submit them all together to be graded in a single submission. I just don’t see any collector caring about that.

I will also add that for a set of any size, especially if it’s a high grade set, it’s just not possible to pull it off.

Not only that, but the cert numbers are only relevant to the extent that they tell you something about when a piece was graded. But having them graded sequentially doesn’t add anything that a collector would really care about. Is the 1952 topps complete set in PSA 7 worth less simply because the certs aren’t sequentially numbered? Or worth more because they are?

I just don’t see anyone who would ever care.

I suppose the owner of such a set could attempt to sell it for a premium, claiming it as something special that deserves an extra premium. But I have a hard time seeing anyone who would be willing to pay extra for it. I’m guessing it would be received about as well as the fellow running around with photos with a very tenuous passing resemblance to baseball players, and trying to sell them for outrageous prices.
