You have an XF/AU Morgan dollar that is a very common date but has a very nice "Die Crack" through the "UM" of "UNUM". Bad News, it has been cleaned...
Where did you get it and might we inquire what you paid for it?
Grading XF/AU:
1) Wear on Lady Liberty's head and hair.
2) Slight wear on the reverse of the Eagles feather tips and breast
3) To many bag marks on the obverse and the fields are full of scratches (Signs of Cleaning).
This coin has been in circulation although the period was rather short. There should be some type of very light graying/toning occurring and accumulated "Crud" in the devices, there is none. The brown on the edges typically happens after a silver coin has been "Dipped" in Sterling Silver cleaner but it appears they used the paste form and brush with this type of cleaner.
The rim dings on the obverse at about 11:50 - 12:00 also makes a statement about circulation and PMD. I am excusing the rim damage at 3:00 on the obverse as I am thinking it was cut off in the scan, the reverse seems fine.
I would have to grade this XF45 - AU55, I am not experienced enough yet to get it nailed down to the exact grade so I always go one under and one over what I think it might be, in this case AU-50.
