Most uncut sheets are already quite valuable, and by cutting them they might be worth only a tiny fraction. That's why I don't think there is a number that correlates to the individual cards. Sure, if you have a T206 Wagner on it it's more valuable than if you don't, but to assume a sheet is just a cut away from becoming individual PSA 9's is the wrong way to look at it.
P.S.- The word is spelled "grammar"
