Half Guinea 1751 grade please

Welcome to Numista. Two things. Your photos are rather blurry for grading purposes and I think I see the date 1759 and not 1751.

It's the same J as at the beginning so it's probably 1751, but yes quite blurry.

I'm not as confident as you with the photos provided. His strike and date is closer to the rim and his last digit seems closer to the 5 giving me doubt about the last digit. Better photos would clarify the issue.
