From the angle of your pictures, I can't really tell the exact grade. I would have to say it is at least EF grade if not better. Non-angled pictures are best for determining the grade. As far as getting it certified by a 3rd party grader, that would depend on the condition. If it is almost uncirculated(AU) grade or better that might be a good idea.

Those are the top retail values from PCGS.com. As you can see with this issue, grade is VERY important. Some Morgans are quirky like that, inexpensive in low grades but INCREDIBLY expensive in top grades. This is because in some of the Morgan years, the whole mintage was released for circulation, leaving very few in Mint State. Also, many Morgans were melted down by the mint over the years for a fresh supply of silver. Other years, bag upon bag fresh from the Mint sat in bank vaults until the 1960s. Those years can be readily found in high grades.
Also, never clean coins! All it does is damage them. Especially ones like this that are potentially worth hundreds or thousands!
