Looking for help ... 1842 Seated Dollar Grade 0

[J&B 5858]

Thanks in advance on any input on how you would grade this 1842 Seated Dollar.

From those pics AU Details.

Well....first off, what I know about grading Seated coins likely wouldn't fill a thimble (my old boss liked Seated coins, so he always was the one to look at them and grade them in the shop I worked at and I never collected them), but I can say that the dollar in this thread looks cleaned to me.  And I also suspect that the 1855 half from your other thread has been cleaned as well.  The toning on that one just doesn't look right to me.

Probably AU details; you can tell its been cleaned because of the hairlines.
