1940 Walking Liberty Half Dollar Proof Help With Grade

I surely would, after a quick peek at Red & Blue Books value at MS-65, and I think yours may do even better than that.

I'm also not an expert on these, but I agree it looks a bit unusual. The surfaces look too uniformly reflective, and there seems to be a lack of detail in the head, robe lines, and eagle breast for a proof strike. I certainly could be wrong, and I would suggest PCGS or NGC if you get it graded.

Yep this sure does look like a plated business strike . If that coin was a proof it would have some toning to it . This piece has absolutely no toning at all , just high gloss shine .

Here's the reverse of a proof from the same year. Note the absolute hammer strike on the eagle's feathers and breast. On your coin the breast is almost flat, and the lower feathers aren't well differentiated. It also doesn't have that glossy look, and exhibits expected toning.

Bob , Because your Niece photographed your coin doesn't prove that it's a proof unless she is a well seasoned coin collector . The late consensus is trying to inform you that your coin is more than likely a Business strike , not looking to put anyone down . While not recommending it , maybe you should have it slabbed and authenticated .

Unfortunately I am also going with plated. Fields on the obverse have a very unusual granulated look. Low points in all of the details look to be filled ( very common with plating since you obviously adding material to the surface). And like others have pointed out, lack of detail on high points and a WAY to consistent gloss appears are all red flags. I'd be curious to see what the edge of this coin looks like. If that same "glossy" surface carries into the reeds would be a pretty big giveaway.

Tough call from these photos. But I don't like the little tics and raised bumps on the surfaces. Until sharper photos are posted I'll pass on a grade.

Yes this is valuable enough if proof that the grading cost would be worth it, and it would be a good learning experience for future grading to help distinguish between what might be a weak struck proof, which is really rare, and a plated coin.
