Worth of Green Pahlavi Coronation Medal?

Hi everyone, I have this Pahlavi medal – weighing 49.43grams and 21.6 karats (I tested it). Based on internet research, it appears to be quite rare. Its current melt value appears to be $6435, but I'm wondering what it's value might be, as a rare collectors' item. Thanks in advance for any insight or help any of you can offer.
