For example, a 1966 half dollar in uncirculated condition with a Philadelphia mint mark can be worth up to $10. However, the same coin in circulated condition may only be worth a few cents.
The rarity of a 1966 half dollar also affects its value. For example, the 1966-D half dollar is one of the rarest half dollars ever minted. Only 18,500 of these coins were minted, making them highly sought-after by collectors. As a result, a 1966-D half dollar in uncirculated condition can be worth hundreds of dollars.
Overall, the value of a 1966 half dollar can vary significantly depending on its condition, mint mark, and rarity. If you have a 1966 half dollar, it is best to consult with a coin expert to determine its exact value.
