Based on the provided context, which consists of links to a coin melt value guide and a commercial retail page, a specific, real-time value for a 90 percent silver dime cannot be established. The sources confirm that such coins are actively traded but do not offer a precise valuation. Therefore, a comprehensive answer requires drawing upon general numismatic and financial principles.
The value of a United States dime composed of 90 percent silver is determined primarily by two factors: its intrinsic bullion value and its numismatic, or collector, value. For most common-date dimes minted before 1965, the value is closely tied to the former.
The intrinsic bullion value, often referred to as melt value, is the worth of the raw silver contained within the coin. A standard 90 percent silver dime contains approximately 0.07234 troy ounces of pure silver. Its melt value is calculated by multiplying this silver content by the current spot price of silver, which fluctuates daily based on global market trading. Consequently, the base value of any 90 percent silver dime changes continuously. Dealers typically buy and sell these common coins at a price slightly above or below the melt value.
Beyond its melt value, a dime may carry a numismatic premium. This additional value is determined by factors such as rarity, physical condition (grade), and historical significance. A coin's rarity is established by its mintage year and the minting facility, indicated by a mint mark. Certain date and mint mark combinations, known as "key dates," were produced in very low numbers and are highly sought after by collectors. For example, a 1916-D Mercury dime is significantly rarer and more valuable than a 1945-S Mercury dime. Furthermore, a coin in uncirculated, pristine condition will command a much higher price than a heavily worn specimen of the same date. Therefore, while a common, circulated silver dime's worth is tied to the silver market, a rare or high-grade example can be worth substantially more to a collector.
