Long post, so grab a drink and a snack, sit back and see if this helps.
If I miss anything or get something wrong, other members comments on my post are more than welcome.
These photos are better, but still not what's needed to give you a informed guess as to the grade. I can't see how much wear the coin has on the high points or the contact marks in the fields. In fact it's even hard to see the mint mark in the reverse picture.
If you want to try to guess at a grade yourself, go to the PCGS Photograde Online page.
https://www.PCGS.com/photograde It's free and it's fun to use! Click on Dollars and then
Morgan dollar, that will take you to this screen
https://www.PCGS.com/photograde#/Morgan/Grades It gives you photos to compare to the condition of your coin, to get an idea of the grade from PO-01 to MS-70 (or for
Morgan dollars MS-69.)
Once you have a grade in mind, go back and forth between the photos above and below that grade until you feel you've zeroed in on what you think the coin should grade if you were to submit the coin to PCGS. THEN when you have the grade you have decided on, use a price guide to figure out the coins value. I use
http://www.numismedia.com to get the "Fair Market Value" for any US coin. This link will take you directly to the
Morgan dollar values.
http://www.numismedia.com/rarecoinp...&search7=any If you think that gives you a realistic idea of what the coin should be worth, then it's up to you where to go from there. If you still don't feel that you're in the ballpark, take the coin to a coin shop or a coin show in your area. Get a few dealers to set a value and grade for you and compare that to the grade and value you set.
The only way to be
almost sure of the value would be a Third Party Grader, such as PCGS, NGC or ANACS. These 3 are the most accepted of the graders for
US coins. You'll have to do some research to figure out if a coin is worth grading. Most numismatist use a value of $150 to $200 as the lowest price for a coin that should be graded, but once again, it's totally up to you.
With that said, most collectible coins are worth less than the lowest value for grading. A certification will cost money that you may not be able to recover when you sell the coin. The reason I said that grading is ALMOST a sure way of knowing the value of a coin is that everyone gets coins that are incorrectly graded now and then.
Welcome to the Coin Community Family and I hope you have fun and find lots of valuable information here. I'm not an expert. I just love coins and I hope the answers I give are as accurate as possible.
