1893 Indian Head Cent

Sorry. All the seller's pics are at a slight angle. Here's another shot but I'm not sure it'll tell you much more.

At this point, I lean toward AU-55 and possibly cleaned and re-colored.

with coinfrog , nailed it to a tee , AU-55 .

I see almost certain wear on the ribbon and an unnatural coloring. I would not buy this without much better pics.

twslisa, although a collector of toned U.S. coins for over 20 years, my experience and comfort is in silver coinage. Copper I am far from comfortable with, and there is a wide range of opinions on this very type of toning from people whom I respect.
I remember about 10 years or so ago when there was a rash of blue toned Indians getting graded by PCGS. The consensus at the time was that the coins were being dipped in MS70, which is what was imparting the blue toning. Rick Snow, who has forgotten more than I will ever hope to know, believes that the MS70 is only allowing the color that is already present on the coins to come through. To this day, it is a highly debated topic. FWIW, I have gravitated towards what Rick feels.
To learn more about this, I suggest going across the street to the collectors universe site and doing a search. There is a ton of information available, including posts from Rick.
As for the grade of the coin in question, I'm seeing enough signs of wear to call it an AU-58.

Will do, guys. I look forward to seeing the coin in person. I've bought a few coins that weren't as good as I initially thought; if I liked the coin anyway, I have usually written it off as an inexpensive education. This seller called it BU/UNC--I'm not sure what range of grades would fall under that description. I had assumed that it would mean the coin would be MS 60, at least, since AU basically acknowledges that the coin is in circulated condition. If anyone hcan provide clarity on that, I'd appreciate it. Anyway, if you guys are all seeing wear that I missed, clearly my eyes need more education on grading from photos. Not sure whether a bad rating is deserved, since the seller also recommended in the description that the viewer look closely at the photos and judge for themselves. I'll try to post better photos once I get the coin.

I've been seeing graded, toned Indian cents quite a lot; recently picked up a couple at the Denver Coin Expo. If it really is something that has been done artificially that's a shame.
