1850 Large Cent ~ Please Grade

That's a nice looking coin, I'd go AU. It looks like there is a little wear on the curls above the shoulder & ear, & also on the coronet above the L in Liberty. I'm a little suspicious of the color, possibly dipped & retoned?

The details on this coin are definitely AU55 in my opinion. I agree that the color is suspicious. If you look at the reverse, you can see the difference in the field and in the devices of ONE CENT. It has a cleaned appearance, though I don't think it was harsh. I don't think the coin has necessarily been artificially retoned. I think the color difference is the copper reacting with whatever cleaning agent was used.

AU++ may be MS-60 if a grader likes it
