Grade Of 1821 British Crown?

I'd say VF20. Cleaned?

Oh, okay. Could be. Great looking coin nonetheless!

G'day,
G'day, I'd rate the obverse a full grade better than the reverse. You can still see a lot of detail in H.M.'s hair, and around his eye. Although the high points are worn, all design elements are evident.
The reverse contains most elements in outline only.
I wouldn't necessarily conclude that this has been cleaned.
Apart from even wear, the coin has no significant dings.
It is very uncommon to find a coin of this era in better condition, and plenty of examples are more worn &/or more dinged.
I'd put it between Fine and VF: say, Fine+.
Please satisfy my curiosity: what inscription is there on the edge: "primo" or "secundo" ?
I put together a year-set of 1820, and I had to pay a lot to get a crown as good as this.

Yes, I also noticed how nicer the obverse looks--do strike issues come into play?

I hope this doesn't come off as wrong, but why does George III's effigy so resemble Nero? Clearly they're going after an Imperial Roman style, but the particular resemblance is uncanny, and I'm sure there's a better explanation than mine.
