BGS sub-grades, how much more are 10's?

MrNearMint

After looking at a few Bgs 9.5's with and without 10 subs, I see there can sometimes be a big difference in price.
What's a fair price increase for one 10 sub?
Does it matter what sub-grade it is?

What's a fair price increase for one 10 sub? Depends too much on the specific card
Does it matter what sub-grade it is?yes, most people weigh surface the least >>
