The 1952-D dime is not a particularly rare coin, but it is one of the more popular dimes from the 1950s. This is due in part to the fact that it was the first dime to be minted in Denver, Colorado. The Denver Mint opened in 1906, but it did not begin producing dimes until 1952.
If you have a 1952-D dime, it is worth taking a close look at it to determine its condition. If the coin is in good condition, it may be worth having it graded by a professional coin grading service. This can help you to determine the exact value of the coin and make it more marketable to potential buyers.
