The price of gold fluctuates. If it is gold jewelry, I suggest you go to various gold shops near where you are located. Generally, gold shops will recycle it, and the price will be reduced by 30-60 yuan/gram. For example, today's gold price is 260 yuan, so the price of gold shop is 300-360 yuan/gram, and the price of recycling is about 270-300 yuan/gram. Specifically, you should go to the physical store for consultation.
If you want to sell physical gold bars, it will be much easier. Just go to the local bank or pawn shop to sell it. The price is similar to that of international futures gold. The latest price 1286 USD/ounce, about 255 yuan/gram.
By the way, does the brand you bought have a physical store in the local area? If not, other gold shops may have to check the purity before recycling.
