In that condition I don't think they are worth a whole lot over melt. Then again I'm not a toning expert. I'm thinking that dark toning may not add any value, but I could be wrong. I'm sure one of our toner fans will come along and tell you for sure.
All 3 (1886 P, 1888 O, and 1921 D) are common dates in the Morgan series. I would say the '86 is in AU condition, and that type of toning isn't going to bring any premium, the '21-D looks AU too; and the 1888 O is in Good condition. They're pretty much worth silver melt value, so a little over $20 a piece.
