I love these early machine struck coins. Generally struck from tired dies.
This one is not too bad.

Dear maudry, your coin details:
Qajar, Nasir al-Din Shah, 1297 AH, AR 2000 Dinars, Tehran mint (AH 1264-1314/1848-1896 AD)
Reverse (First photo): the Farsi legend: السلطان ناصرالدین شاه قاجار , "al-Sultan Nasir al-Din Shah Qajar " in the center circle within wreath and the mint " Tehran طهران " is at the bottom.
Obverse (Second photo): Crown above lion and sun within wreath, the date "1297 ۱۲۹۷ " is at the bottom. The denomination value is " Two Thousand Dinars دو هزار دینار " below the lion.
