The coin in question is a 1974 Washington Quarter minted in Denver, identified by the mint mark 'D'. This quarter, part of the widely recognized Washington Quarters series, has a denomination of 25 cents, which is equivalent to a quarter. The coin is made from a Copper-Nickel clad composition, featuring a classic design that portrays the profile of George Washington on the obverse (front) side and an eagle on the reverse (back) side, emblematic of American heritage. With a diameter of 24.3 millimeters and a weight of 5.67 grams, it is characteristic of standard U.S. quarters. This particular issue had a significant mintage, with 353,160,300 coins produced in that year at the Denver Mint. As a common coin, it generally does not carry a high premium over face value unless it is in unusually high grades or possesses unique attributes. Nonetheless, it is a notable piece for collectors and an excellent representation of mid-20th century U.S. coinage.
