Double Die Errors: These occur when the die imprints the design on the coin twice, leading to a doubled image. Such errors can significantly increase the coin's value, sometimes making them worth thousands of dollars.
Off-Center Strikes: Coins that are not struck in the center can be highly valuable, especially if the date or state name is still visible. The more off-center the strike, the rarer and more valuable the coin.
Missing Clad Layer: State quarters are usually composed of a copper core with a nickel coating. If a quarter is missing this outer layer, it can result in a copper-colored appearance on one or both sides, making the coin extremely valuable.
Wrong Planchet Errors: Sometimes quarters are struck on planchets (blanks) meant for other coins, such as nickels or dimes. These mistakes are rare and can fetch a high price from collectors.
Mule Errors: These occur when the obverse (front) and reverse (back) dies from different coins are mistakenly used together. Mule errors are extremely rare and can be worth thousands of dollars.
Clipped Planchets: A clipped planchet error happens when a coin is struck on a planchet that has a portion missing, usually due to a misfeed during production. Such coins are unusual and can be valuable depending on the size and location of the clip.
