how much is a 1964 silver dime worth today

[StEverly]

That's a great question! It's always interesting to look into the value of old coins.

Based on the information from Littleton Coin Company, a 1964-D Roosevelt silver dime in "Average Circulated" condition is listed for a retail price of $19.25. The "D" simply means the coin was struck at the U.S. Mint in Denver.

The main reason this dime is worth significantly more than ten cents is its silver content. As the source points out, 1964 was the very last year that U.S. dimes were minted with 90% silver for circulation. After that, due to rising silver prices and a coin shortage, the composition was changed. This makes any 1964 dime a valuable piece of history, sought after by collectors and investors for its precious metal content.

Keep in mind that this is a retail price from a specific dealer. The exact value can vary depending on the coin's specific condition and where you are buying or selling it, but this gives you a solid idea of what it can be worth.
