Iran, Quarter Qiran, 1800's. 
 
Important Note: This item is not for export. Many countries currently have sanctions in place for cross border trade of Iranian goods preventing export and import. 
 
The wear to this coin is making it very difficult to identify which type and year so this is being sold on the understanding that it could be an unknown date between the ranges below.
 
Silver Iranian coins from this period are relatively scarce in any condition.
