The half coin is half a full coin: about 4.06 grams of gold at 900 fineness. It is popular as a gift and for saving with a smaller sum.
What moves the price
The world gold price (per ounce) and the free-market dollar rate: together they set the value of the gold inside the coin.
The coin's premium, or ‘bubble’: the gap between its market price and the value of its gold, which rises and falls with demand, inflation expectations and central-bank supply.
The calendar: demand for the smaller coins usually rises before Nowruz and in the wedding season.

Common questions
Why is the half coin's premium usually higher than the full coin's?
Gift demand for the smaller coins is high and their supply lower, so the market pays more relative to their gold.
