Take the photos from directly overhead with lighting placed about 10 & 2 o'clock at a 45 degree angle so the light bounces away from the lens. Taking photos at an angle tends to hide marks that may affect the grade. Chris
Next to the 1921 the 1887 is the most common Morgan Dollar. Don't expect a whole lot. Like Chris said better photos would have to be provided if you want anyone to offer a grade or value.
Looks like a nice one. Still a lot of feathers on the eagle's breast. I know they minted about 20 million so at least $35 and UP. The "O" and the "S" had 11+ million and 1+ million respectively and would bring a higher premium. But looks like you have a very nice Morgan there.
