The 1978 half dollar is part of the Kennedy series, minted since 1964.
Most 1978 half dollars are made of a copper-nickel clad composition.
Circulated coins typically hold face value, but uncirculated coins can be worth more.
Special collector's editions, like proof coins, may fetch higher prices.
Condition is key: 'Fine' to 'Mint' state can significantly affect value.
Look for errors or varieties, such as double dies, which increase value.
Check for silver-clad varieties from mint sets that are more valuable.
1978 half dollars minted in Denver (D) or Philadelphia (no mint mark) have no silver.
Always consult a coin expert or recent price guide for the most accurate valuation.
