What is 1 troy ounce-999-fine-silver dollar from Letcher mint dated 1974 worth?

Answer 1

It's one troy ounce of silver, therefore its value is based on what silver is selling for at the time of sale. You can get a little more than international market value at auction, usually or by advertising. Right now; April 22nd '09, with silver at 12.30 and expected to rise, it'll get about 15 bucks. A dealer will give you less than market value because they want to be able to make a profit when they resell it.
