I agree with the upthread comments: leave the coin in its original state and have it graded by a third-party grading company.
Clearer photos would help us get a better feel for the possible grade range for your coin. One way to do this is to use your cell phone. Place the phone on top of a stack of 3 or 4 books, with the camera hanging over the edge. Place the coin on a dark cloth surface. Use natural light. Focus the camera so that the coin fills the frame and is in sharp focus. Make sure the coin is oriented properly for the photo. You can use the CCF image optimizer to adjust the image for uploading.
Again, congratulations on the find. It's a rare date and will attract solid collector interest.
