The rarity of a coin is often determined by its mintage, which refers to the number of coins produced. If a particular Bicentennial Quarter has a low mintage, it may be considered rare and more valuable to collectors.
The condition of a coin is a critical factor in determining its value. Coins that are well-preserved and exhibit minimal wear and tear, known as a high grade, are generally more valuable than coins in poorer condition.
Coins with minting errors or unusual varieties can be highly sought after by collectors. For example, a Bicentennial Quarter with a printing mistake or a unique design variation may fetch a higher price.
Coins that have historical significance or are associated with notable events may attract collectors. The Bicentennial Quarters, minted in 1976 to commemorate the United States' 200th anniversary, have historical importance.
The demand for specific coins within the collector community can drive up their value. If a particular coin is highly sought after, collectors may be willing to pay a premium for it.
