The origin of the coin would be one of the United States Mints. You don’t mention which mint or the grade of the coin but it contains .9675 of a troy ounce of pure gold. Average pieces (VF) of either Philadelphia or San Francisco would bring about a 5% premium over the gold content. A Carson City Mint example (cc mint mark) would bring at least a 50% premium over gold in average condition.
