The 1977 Jefferson Nickel is a staple of U.S. currency, part of the long-running Jefferson series.
Minted in Philadelphia and Denver, no mint mark indicates Philadelphia, while 'D' denotes Denver.
Standard composition: 75% copper, 25% nickel. A consistent alloy since 1866, barring wartime changes.
Circulated value is generally face value, but uncirculated or proof coins can fetch higher prices.
A full-step designation, indicating sharpness of the Monticello steps, can raise a coin's value.
Special collectors' sets, like the Uncirculated Mint Set, may include premium 1977 Jefferson Nickels.
Proof coins, struck at the San Francisco Mint with an 'S' mark, are sought after for their finish.
Always consult a professional coin grading service or guidebook for the most accurate valuation.
