The value of a silver coin today is determined by two primary factors: its intrinsic metallic or "melt" value and its numismatic or "collector" value. The final worth of a given coin is typically the higher of these two figures.
The intrinsic value is based directly on the amount of silver the coin contains and the current market spot price for silver, which fluctuates daily. For United States coinage, a critical date is 1964. Dimes, quarters, and half-dollars minted in 1964 or earlier are composed of 90% silver. After this date, the silver content was either eliminated or significantly reduced. For example, Kennedy half-dollars from 1965 to 1970 contain 40% silver. To determine the melt value, one must know the coin's specific silver content by weight and multiply that by the current price of silver. This calculation provides a baseline value for any silver coin.
Beyond this melt value, a coin may possess numismatic value, which is determined by factors such as its rarity, historical significance, condition or grade, and overall collector demand. A common, heavily circulated pre-1965 silver quarter will likely be valued at or very near its silver melt price. However, a rare date coin, a coin with a specific minting error, or one preserved in pristine, uncirculated condition can be worth significantly more to collectors than the value of its silver content alone. Therefore, a comprehensive valuation requires identifying the specific coin, assessing its physical condition, and checking its value in both the bullion and numismatic markets.
