1921-D is one of the most common dates for Morgan Dollars -- worth about $9 in circulated condition.
answer above is WRONG--the melt value alone is worth more than $9 which is about $20 now for an ounce of silver. 9/8/2010. depends on the condition of the coin...take it to a REPUTABLE dealer or to a coin show to get a realistic appraisal. failing that you can go to a coin value webpage such as pcgs.com they have a price guide which will give you a better idea. a double die--may be real or it may have been forged...again a REPUTABLE dealer will be albe to tell you. can not say without pictures etc. but certainly more than $9
It depends, this silver dollar, which since you say has a "D" on it, which means it is a Morgan Dollar, is not worth much over its bullion value in this condition. As the price of silver has risen (about $35 per ounce as I write this), the silver value has now exceeded its numismatic value. Keep in mind that a silver dollar is NOT one ounce of silver. The coin is 90% silver and has 0.77343 of silver in them
