Mispunched Dates: Look for quarters with incorrect or partially visible dates, which can significantly increase their value to collectors.
Off-Center Strikes: Check for quarters where the design is misaligned or not centered properly on the coin, leading to an uneven appearance.
Double Die Errors: Identify quarters with designs that appear doubled due to a misalignment during the minting process. This creates a noticeable duplicate effect.
Wrong Planchets: Some quarters might be struck on incorrect or foreign planchets, which can include different metals or sizes, making them rare finds.
Die Cracks and Breaks: Examine quarters for cracks or breaks in the die that can create unique patterns or details on the coin’s surface.
Mint Marks: Be on the lookout for quarters with incorrect or missing mint marks, as errors in mint mark placement can be valuable.
Inverted or Reversed Designs: Look for quarters with upside-down or reversed designs, which can occur due to errors in die alignment during production.
