The one gram coin is the central bank's smallest gold coin: about one gram of gold at 900 fineness, which makes it the least expensive way to buy a gold coin.
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.
