The quarter was the first 25-cent coin to be struck in the United States. The first quarter featured a bust of George Washington, designed by Robert Scot. It was minted from 1796 to 1807 before the Draped Bust design replaced it.
Here’s a breakdown of what makes a bicentennial quarter with "D" mint mark so valuable:
* Mintage: The "D" mint mark indicates that the quarter was minted at the Denver mint, which produced fewer bicentennial quarters than other facilities (the "P" mint mark indicates the Philadelphia mint, while the "S" mint mark indicates the San Francisco mint).
* Rarity: The "D" mint mark is significantly more rare than other mint marks for bicentennial quarters. Out of the ~420 million bicentennial quarters minted in 1976, only about 26 million were produced in Denver, making them more scarce and therefore more valuable.
* Historical significance: 1776 was the year of the Declaration of Independence, making bicentennial quarters with a "D" mint mark highly sought-after by collectors and investors as symbolic pieces of American history.
It's important to note that the condition and preservation of the coin can also affect its value. Coins that are in excellent condition (such as mint state or nearly so) are typically worth more than those that are heavily circulated or have significant wear and tear.
Before buying or selling a bicentennial quarter with a "D" mint mark, it's always advisable to consult professional coin experts or consult numismatic publications for the latest and most accurate information on its value and rarity.
