The 1 gram gold coins are the smallest coins issued. Coins of 1 gram are not very common. Most coins are minted in 1 troy ounce (31.103 grams) or in smaller denominations thereof, such as 1/2 troy ounce, 1/4 troy ounce or 1/20 troy ounce.
Investment coins of 1 gram are very rare, but collector coins are sometimes minted in this different weight. The low weight of these gold coins makes them available for almost every budget.
One of the best-known 1 gram gold coins is the panda coin from Chinese mint China Gold Coin Corporation. As of 2016, all gold panda coins are minted in a different weight. The combination of the different weight, good quality and the annually updated design, makes the gold panda coin very popular among collectors.
