Not an expert on the series but I love half dollars.
I'll say 65 FBL. Looks like a ding on the ear and at the corner of the mouth. I don't know about the black spots. Still a good looking coin even with the black.

Collect for the love of the hobby, the beauty of the coins, and enjoy the ride.
well after much debate i decided to crack the coin and soak it in acetone, and what do ya know the black spots dissapeared! the coin looks great now! You can still guess the grade though
That acetone soak may have impaired the skin, some, and dampened down some of the richness in the colors. That "black stuff," also, appears to have been tarnish. JMO...
if I look under the bell, on the right side, the green is almost gone. >>
My experience is, yes. It's very fickle, though. Sometimes it's very subtle, other times, more apparent. It does something to the "skin" that tarnish lays on, I'm sure of that. It usually won't hurt the market grade of the coin, though. However, that's principally because nobody knows what that tarnished skin looked like, before. In fact, when I first started noticing this, I did a lot of "double-takes." By that, I mean, I'd "know" something looked different, a little less-flattering to me, but I couldn't quite put my finger on what it was. A lot of the time, it's just that plum intangible. One really has to pay attention, sometimes, to see it.
I've seen it too. Very subtle change, particularly on delicate toned proofs.
I suspect it has something to do with the chemical reactivity of acetone. There is no question that acetone breaks disulfide chemical bonds. And we know that sulfur chemistry plays a huge part in silver toning.

<< <i>heres what it looks like now after about 10 minutes soaking in acetone. I will try to get the rest off tomorrow which i dont think will be a problem. >>
I have no experience using acetone, however I think that it looks nice the way it is now. The toning that the coin exhibits in your first picture is very deep. If you remove the rest of that spotting who knows what will happen to the lustre/surface. Literally, who knows? Enlighten me

There's something still don't look quite right about the ear but the soaking cleared up the corner of the mouth.
I'll give it a 66 FBL.
However, I wonder if you would break out a $600 coin, PCGS Price Guide price to soak it.
Still it's a good looking coin.

I'll go MS65 FBL
........that's been my experience with acetone as well
would acetone remove "Natural" toning?
