* Condition: The condition of a coin is one of the most important factors in determining its value. A coin in excellent condition will be worth more than a coin with scratches or wear.
* Rarity: The rarity of a coin will also affect its value. Some coins are more rare than others, and this can make them more valuable.
* Silver content: The silver content of an 1850 quarter is also a factor in its value. The silver content of an 1850 quarter is 90%.
In general, an 1850 quarter in good condition will be worth between $5 and $10. However, a rare 1850 quarter in excellent condition could be worth much more.
