FAQs

How can I tell if my Kennedy Half Dollar is valuable?

Check for unusual finishes (matte or satin), doubling on letters, or specific varieties like “Accented Hair.” Condition is key — high-grade coins bring the highest value.

Do Kennedy Half Dollars from the 1970s have any silver?

Only the 1970-D has 40% silver. Other coins from the decade are primarily copper-nickel unless from special silver sets.

What is a Doubled Die Obverse?

It’s a mint error where the design appears doubled, most visible on text. This significantly increases a coin’s value.
