ok um does anyone kno how much a 1890 morgan silver dollar coin would run for?

Like so many other people on Yahoo Answers, you have left out key information that we will need to answer your question intelligently:
First, the mint mark, if any, is located on the back below the eagle. The possibilities are no mint mark (Philadelphia, the most common), O (New Orleans), S (San Francisco), and CC (Carson City, the scarcest).
Second, condition of your coin makes a big difference. A heavily worn coin will be worth barely over the value of the silver content, which is about $11. A coin in as-new condition is worth anywhere from $40 for Philadelphia to $400 or more for Carson City.
I don’t mean to be rude here, but there are a lot of non-collectors here that genuinely don’t know how to ask this type of question. Earlier today, I saw someone asking about a Confederate banknote dated 1867 – two years after the Confederacy ceased to exist. If you need more info, e-mail me through Yahoo Answers.

join some communities or groups in orkut or yahoo related to coins. U can interact with a lot of collectors and dealers. I am myself a part of some of them. If u need further help, drop me a mail…
