1814 Capped Bust Half Dollar For Grading & Overton

I'll take the first shot at it...F15. The odd color leads me to believe it was cleaned. Wicked die breaks on the reverse

Really cool Bust Half!

I'll say mid to high range VF, perhaps VF-30 or VF-35.

I grade this coin at VF30, maybe VF35. Prominent die break on reverse add to its appeal. Nice coin overall. I am also looking for an 1814 to add to my collection, and hope to find one like this one.
I am not experienced enough to judge whether the toning is original

Just an FYI: the PCGS slab labeled this coin:







I agree. It's pretty tough to tell what strike weakness happened during the initial strike due to Die Deterioration and what wear has done.

what is going on between the back of the face and the hair?

This coin shows a die clash on the obverse from reverse die AND on the reverse from the clash with the obverse die. You can see parts of the reverse shield showing on Liberty's neck on the obverse, and the reverse scroll showing just under the Liberty's bust and above the date.

The hair shows a weakness due to the die cracks on the reverse not allowing the metal to flow where it normally would during the strike (the cracks relieved the normal pressure that would force the silver to fill the die/coin's details, like on the reverse right wing below the crack. There's an obvious lack of detail there). Overall, pretty cool, IMO.

Understatement of the year!
