Pictures would help, no one on here can possibly attribute a coin they cant see, if it is a week cc or a worn cc there is two different prices. so if possible please take time too take a pic. also I could be wrong but i think Carson City minted coins other than just the morgan dollar, but this list is a break down of just that particular coin. G would go for around 75 VF would go for around 650 AU55 for around 1800 MS62 for around 4,000 MS65 for around 20,000 So as you can see there are a major difference between grades, and without seeing the coin you cant accurately tell it's price.
What denomination coin are you asking about? Once we know the denomination it would help to know the coin's grade.
