- Circulated: A circulated 1890 quarter in good condition can be worth around $6 to $10.
- Uncirculated: An uncirculated 1890 quarter in mint state (MS-60) can be worth around $80 to $100. Higher grades (such as MS-65 or above) can be worth significantly more.
Please note that these values are estimates and actual prices may vary depending on market conditions and specific details of the coin, such as its rarity and desirability. To determine the exact value of a particular 1890 quarter, it is recommended to consult with a professional coin dealer or numismatist who can assess the coin's condition and provide an accurate appraisal.
