PCGS shows a retail price of about $1300, although that may be a bit on the high side.
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
