The worth of a 1964 half dollar minted in the United States, composed of 90% silver, is influenced primarily by its intrinsic silver content. This precious metal component dictates a base worth significantly higher than its face value of fifty cents. External factors such as the spot price of silver, coin grading, and collector demand contribute to the fluctuations in its market price.
The historical context of these coins as the last circulating silver coinage in the United States enhances their significance. The Coinage Act of 1965 eliminated silver from circulating dimes and quarters and reduced the silver content of half dollars to 40%. This event increased the numismatic interest in, and therefore the worth of, pre-1965 silver coins. Furthermore, the inherent precious metal content provides a tangible store of value, making these coins attractive to investors seeking a hedge against economic uncertainty.
