Here's a general guide to the potential value of Kennedy half dollars after 1970:
1. Common Date Coins: Kennedy half dollars minted in large quantities and without any significant errors are generally worth close to their face value of 50 cents.
2. Semi-Key Dates: Certain dates, such as 1970-D and 1975-D, have lower mintage numbers compared to other years. While they are not considered rare, these semi-key dates can fetch a slight premium over face value, typically around $1-$5.
3. Silver Content: Kennedy half dollars minted before 1965 contain 90% silver, making them valuable for their silver content. While their value fluctuates based on the current market price of silver, these silver half dollars can be worth significantly more than their face value.
- 1965: 40% silver - face value ($0.40)
- 1971-74: 40% silver - varies; typically around $5-15
Rare Dates:
- 1970-S Proof - potentially thousands of dollars
- 1976-D - typically in the hundreds
It's important to note that the actual value of Kennedy half dollar coins can vary widely depending on their specific condition, mint mark (e.g., "D" for Denver or "S" for San Francisco), and market conditions. Consulting a professional coin dealer or referring to reputable coin price guides can provide more accurate estimates for individual coins.
