Tips for Identifying Rare Half Dollars

Check the Date

  • Certain years, like 1948, 1955, and 1970, are key dates for different series of half dollars. These dates often correspond to low mintage or special issues.

Mint Marks

  • Mint marks like “D” for Denver or “S” for San Francisco can indicate where a coin was struck. Some mint marks are associated with rare varieties or low production runs.


  • The condition of a coin, known as its grade, significantly affects its value. Coins with minimal wear, clear details, and no damage are more valuable.

Unique Features

  • Look for coins with unique features, such as the Accented Hair on the 1964 Kennedy half dollar or errors in the minting process. These features can make a coin particularly rare and valuable.

Silver Content

  • Half dollars made before 1971 often contain silver. Coins with higher silver content are generally more valuable due to the intrinsic worth of the metal.


Collecting half dollars can be a rewarding hobby, especially when you come across rare and valuable coins. By paying attention to key dates, mint marks, condition, unique features, and silver content, you can identify and appreciate the rarity and value of these fascinating pieces of numismatic history. Whether you’re a seasoned collector or just starting, always keep an eye out for those hidden treasures that might be worth a fortune.


FAQs About Rare Half Dollars

1. What makes a half dollar coin rare and valuable?

Several factors can make a half dollar coin rare and valuable, including its date of issue, mint mark, condition, silver content, and unique features like design variations or minting errors. Coins with low mintage numbers or those struck for special occasions often carry higher value.

2. How can I tell if my half dollar is made of silver?

Half dollars minted before 1971 are generally made of silver. Specifically, those minted in 1964 are 90% silver, and those minted from 1965 to 1970 are 40% silver. You can also check the edge of the coin; silver coins will not show a distinct copper stripe, unlike more modern clad coins.


3. What is the significance of the 1964 Accented Hair Kennedy half dollar?

4. Why are some mint marks more valuable than others?

Mint marks indicate where a coin was produced, and some mints produced fewer coins than others, making their mint marks more valuable. For example, coins from the Denver (“D”) or San Francisco (“S”) mints might be rarer and more valuable if fewer were produced compared to coins from the Philadelphia mint.


5. How can I determine the grade of my half dollar coin?

To determine the grade of your half dollar coin, you may want to consult a professional coin grading service like the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation (NGC). These organizations use a standardized scale to grade coins based on their condition, including factors like luster, strike, and preservation.
