The value of any card as the next card when hitting depends on what you already have. For example, if you have hard 12, then the value of a 10 is -100% of your bet, since you are guaranteed to bust. The 10 is significantly more valuable if you have 11, for example. It also depends on how you play your hand if it is still alive after hitting. Reasonable assumptions can be applied, such as that you will continue on using basic strategy.

Are you asking for the value of each card for each possible holding?
