I don't buy Details coins unless it is super extremely rare and there is no other way I'll ever own the coin, and I need it for a set. Guess again.
I am at AU53 It is a little hard to tell what are slab scratches and what is circulation. Thats a pretty half Physics.
Very difficult coin to grade from pix. Nonetheless, it's a beautiful piece. I'd certainly love to have that in my Dansco. Obverse: The deepest, white toned scratches seem to be on the holder. Evidence of that appears to show on the star at 2 and 2:30 where you can see the scratch run across the rim and beyond the coin itself. The fifth star on the right including the field right in front of it shows the same scratch marks. The other 'scratches' I'm going to surmise are die polish lines. I do see signs of wear on Liberty's curls and cap. Rim ding at 3 o'clock. Reverse: No doubt shows better than the obv. It'll net grade higher due to rev. I'm going with AU55. Again, very nice coin. Kudos.
The slab would probably get a Details grade. NGC slabs are the toughest to polish out scratches. Great looking half. AU55
Nah, you didn't insult me. I've got thicker skin than that. I've been on forums for over 20 years. What I will say is, NGC slabs in-particular get real scratchy. Many of the lines you see are slab scratches.
I am going to guess MS-60 something, and a beautiful example. Congrats! I am curious about those Die Polish Line which @masterswimmer mentions: in general, how can one distinguish die polish lines from mere hairline scratches from cleaning?
So, just looking at the obverse, we have a wide variety of lines and marks.... 1. Marks on the slab - that long, thin, white line to the left of her face that carries across all devices, and off the edge of the coin... that's a mark on the slab. You can see two more prominent ones behind her shoulder and into the stars. 2. Old toned scratch - across her cheek and under the eye, there is a thin, black streak. This is a very old scratch that has toned over. You might notice something similar across her chest. 3. A scratch - if you look in the field under her chin, there's a bit of a curved line... that's an actual scratch. It is very mild, but the light just caught it. 4. Die polish - one of the keys for die polish is that it seems to go "under" the devices. Look in front of her nose - those lines go across the fields, but don't cross her nose. That is because on a die, the field is actually the highest part... any polish will be "above" the devices. 5. Actual hairlines - there's a few. You can see them most obviously behind her head. Old coins like this are often forgiven a few hairlines. 6. Planchet striations - one of the key identifiers of this variety are the parallel lines obverse from the rim into her bust. These are as-made, and seen on nearly every example of this coin.
I finally found Dick Grahams' book (Reeded Edge Half Dollars) and after much deliberation (I suck at attributions) I put this beauty as an GR-13.
