My current #1 interest area is Draped Bust half cents by Cohen variety. There are 13 varieties of the 1804; this is my fifth one. The C-6 is one of the "Spiked Chin" varieties, Rarity 2. From the look of the obverse image it looks like I need to redo my camera techniques. The reverse image is much better.
I like the coin. I like all the Spiked Chin varieties. But I think your auto focus decided it was taking a picture of the slab obverse and not the underlying coin. Slab scratches might have fooled it.
I would be a bit careful when you see sharp coins like this with lots of details, but dark spots. I have an 1803 C-4 like this in my collection. I graded it EF-45. When it came time to sell, I got some blowback over the spots which reduced the selling price. I am not saying that the coin undesirable, but I am saying that you should not pay a strong price, relative to the sharpness grade for it.
I use manual focus, so that's only a problem if I don't do it correctly. I think my lighting is the major problem.
very sharp coin, Kanga. Spiked chins are very cool. I have one, raw, about G6, the rev. cuds are ridiculous. I think it's a Cohen 6. I'd love to have one in higher grade.
There is only one known die pair for the 1807 half cent. It is fairly common although the early die state, which shows dentils, is considered to be scarce and worth a premium. The piece you have shows the characteristics of the early die State, but the state a preservation probably precludes a significant premium.
