Grading Vintage Autographs - How Do High Grades Affect Values?

While I have a few encapsulated signatures which are graded, how do high grades affect the value of a signature? Case in point, I recently acquired the Jackie Robinson signed GPC below. The postcard has, without question, one of the nicest Robinson signatures I've ever seen. The GPC, itself, is postmarked 1957 and addressed to a Brooklyn address. I don't think it's unrealistic to think this signature could grade a 10. I think you'd be hard pressed to find a better GPC out there. So, my question is, would grading the signature affect its value (ie, make it worth more (and hence, justify grading it) if the signature does grade out a 10?

To be honest, no direction, but...

As for the question regarding authentication or grade cert, I was actually referring to the grading, i.e., when the signature is authenticated and then also assigned a number grade. In terms of authentication, I'm not worried about the signature being genuine - it unquestionably is. But I do understand the point that having Richard Simon, PSA, JSA or the like authenticate the autograph could make it an easier sell for those that want/demand 3rd party authentication.
Working off the assumption that this item will easily pass authentication 100 times out of 100, any collector can see the quality of the signature with or without a number grade assigned by PSA/DNA. Once it's authenticated, it's guaranteed to get a grade of either 9 or 10, which will only relate to the signature itself. The number has absolutely nothing to do with the condition of the rest of the item.
I would definitely encapsulate with a blue flip rather than have an ordinary authentication that requires DNA swabbing. This particular signature is so clean, crisp, and dark that requesting a number grade can only enhance the value, but it won't enhance it by much compared to merely having it authenticated and encapsulated.
In the end, I think you should treat it like grading cards. Will you grade a 2009 Topps common card? No. Will you grade a 1933 Goudey common card? Quite possibly. Will you grade a 1933 Goudey Babe Ruth? Yes, definitely. With that logic in mind, and if I was the owner of a Jackie Robinson autograph, I would have it graded.

I wasn't suggesting that a duller signature should be or actually is worth as much as a dark, rich signature, only that a number grade is not necessary for even the most novice collector to tell the difference.
This signature is a very solid 9 with a real shot at getting a 10. If OP were to have it encapsulated as authentic without a number grade and a collector who only is interested in signatures with a number grade wanted to buy it, this potential buyer would have to know that he could always very easily send the already authenticated slab to PSA to get a number grade added to the flip. That is why the increase in value for having a number grade on this particular autograph will be nominal. However, getting it authenticated and encapsulated with a blue flip is very important and will unquestionably add to the monetary value.
There is no reason not to ask for a number grade in this case, since it's so obvious that the grade will be high, assuming it passes authentication.
<< <i>That auto would most likely grade a 9 (small shot at a 10) and yes the grade will increase the value. >>
I would have to agree with this poster, if you slab that auto with a Mint 9 grade, it would definitely increase the value over having it slabbed with no grade. If it comes back a 10, then you've got a home run on your hands as I've never seen Gem Mint 10 Robinson auto. I've seen 9s go for between $1000-$1300, so I think a 10 would be around $2000 or maybe more due to the rarity.
