Hi -- Ancients collector here and have been out of the US coin scene for decades. I have a few commemorative halves from when I collected US coins as a kid. Ruddy's Photograde Coin Grading Guide doesn't list commemoratives, so I'm asking for some help. Also, is that spot of toning on the reverse much of a detriment? Thanks so much and merry Christmas to you nice folks in the US forum!
Hard to say from those photos. The wear is really difficult to see, but is there. The bigger issue that I have is determining luster. This coin doesn’t show any in these photos, and the luster is the difference between XF-45 and AU-55 in my opinion
I'll also say AU 55. This is a very attractive circulated example and a nice example of the type regardless of grade.
I'd probably call yours EF-45, with a shot at AU. I don't see much luster, which is going to keep it from AU.
