You'd have to ask a collector. But if you want to know what the silver in that dollar is worth you can look that up at a gold buyers website. I used P3M Refining. http://www.p3mrefining.com/estimator.php All you have to do is enter the current silver price which is shown on that page, select 'silver dollar' and enter the face value. That would of course be 1 for one silver dollar. I just did that for convinience. At the current silver price your silver dollar is worth 8.61USD. Well actually its worth about 12USD. But every coin or gold buyer keeps a percentage to himself.
A Morgan 1882 Silver Dollar has 0.7735 of an ounce of silver.
No, a silver dollar does not equal a half dollar. Instead, in the USA it equals a full dollar.
