Luv the 1902-O quarter picture. Looks like the obverse is clashed under the nose and has chin spikes. Can't wait to here what the expert say about it.
Might be the pics, but based on what I can see I'd say the Buff has been dipped to death and is ungradeable. The quarter, something about it just looks off, can't put my finger on what it is though - XF, maybe a shot at AU. The half, VF.
The quarter looks like AU detail to me, but I have to agree with GDJMSP. It looks off in the color department. The half is what I would expect for a VF-25 in detail for the middle dates.
