Please check your coin again. There's no 2004 "silver eagle half dollar".
American Eagles are large bullion coins minted since 1986 and sold to collectors and investors. They have an artificial denomination of $1 but aren't intended for spending.
All circulation half dollars minted since 1971 are made of copper-nickel, not silver.
If you indeed have an American Eagle .999 pure silver proof dollar coin, its value is largely tied to the spot price of silver on the market. A one-ounce silver coin will always be worth, at a minimum, the spot price of silver. Depending on the condition of the coin and the market in general, it may be worth up to 100% more. Proof coins are worth more than uncirculated coins, which in turn are worth more than lower-grade coins that may have been handled or have scratches, dings, etc.
With the spot price of silver approaching $50, a current check of asking prices for the 2004 American Eagle ranged from $60 for an uncirculated specimen without a gift box up to $109 for a proof coin in gift box. Consider that prices vary among coin dealers and the high price may not necessarily be current fair market value.
