The Grade I think would be MS62 maybe a 63. The value would be around $25-35. I would normally only say $20-30 for the value however the toning adds some nice eye appeal.
I can't tell. Your photos don't show the presence of luster. Based on that, this coin may have been improperly cleaned. Chris
That Morgan has not been cleaned. I think Ed23 is right after seeing the Morgan in the light I would value it at closer to $50.
Liberty's face looks like Rocky's after he went 12 rounds with Clubber Lang. I'd say its about a 62 and I agree with mouse as far as value. I could easily see this fetching $40-50 on eBay.
Using photo enhancement (such as lighten) does not change how the coin should look under proper lighting conditions. The reason these big silver dollars were called "cartwheels" is because the light should radiate around the coin like the spokes of a wheel. I don't see that here. Chris
