United States dimes minted in 1964 and earlier contained 90% silver. Coins produced after this year were primarily composed of copper and nickel, lacking the precious metal content. A significant distinction exists between dimes produced before and after this transition.
The presence of silver in older coinage contributes to its intrinsic value, often exceeding the face value. This makes them attractive to collectors, investors, and those interested in the historical significance of currency. Economic fluctuations and silver market prices can further influence their worth and demand.
