1. Classic Head (Draped Bust) Variety: If the half dollar you have is a Classic Head or Draped Bust variety, it is likely a reproduction or a counterfeit. Genuine 1804 Classic Head half dollars are extremely rare and highly valuable, and their authenticity is often questioned.
2. Turban Head (Liberty Cap) Variety: This is the more common variety of the 1804 half dollar. If your coin has a Liberty Cap design and is in good condition, it could have a value ranging from a few hundred to several thousand dollars, depending on the grade.
3. Condition and Grade: The condition of the coin plays a crucial role in determining its value. Factors like wear, surface marks, and luster can affect the grade.
