Should I get this Babe Ruth autograph graded?

[Augy44]

Thanks for all the suggestions. Looks like it's pretty much a unanimous decision here as far as what should be done. The reason why I was asking was because as of right now I do not plan to sell the signature, but researching some of the past Ruth autographs that have sold at auction, the higher the grade usually reflects a higher premium realized. I understand that the grade is subjective and to each person it may be valued differently, but was just curious what all of you thought on this one just incase I decided to sell. I refuse to pay the $300 authentication fee that PSA charges for Ruth, which was the reason why I purchased this one already authenticated and I don't think it was much more to have it graded. That is also what the original seller suggested as well, as he wished he would have had it graded himself at the time of authentication.
