To Robert on 1921 S Morgan: I think any coin that you are trying to sell for that price in today's market you should get slabbed. I agree with Drew, the color looks to good to match the condition. Rarer Morgans get faked all the time.I'm not saying it is a fake, but, it may have been cleaned or such and that would hurt the price. It would put the buyer at ease if you got it slabbed. If you decide not to slab it, you might want to add some better photos, like a close up of that scratch on the front.
Good luck with it!
