The 1978 Washington Quarter is a piece of U.S. currency, minted in honor of America's first president.
Composed of 75% copper and 25% nickel, this coin has a standard weight of 5.67 grams.
Minted by the U.S. Mint, it was produced in Philadelphia, Denver, and San Francisco.
No mint mark indicates Philadelphia, 'D' for Denver, and 'S' for San Francisco.
Circulated quarters are common, but uncirculated or proof coins can be more valuable.
The value can range from 25 cents to over $100 for high-grade proof or error coins.
Special features like mint errors can significantly increase a quarter's collectible value.
Check for a clear, sharp strike and minimal wear to determine higher worth.
Consult a professional coin appraiser or reference books for an accurate assessment.
