Bank notes cannot be realized directly because they are not in circulation. Moreover, banks and gold shops will not recycle gold banknotes. However, you can resell the money to others, or sell it directly according to the raw material gold. Although it can be realized in these two ways, it won't make much money whether it is resold to others or sold according to raw gold.

Precautions:

Bank gold can be divided into paper gold, gold money fund, gold futures and physical gold. When you buy, you must understand the differences between different investment methods, trading mechanisms, transaction costs, risk levels and so on.

Taking the purchase of physical gold through banks as an example, investment-oriented gold bars are more suitable for investment than commemorative gold bars, and there is no need for intraday trading, otherwise there will be handling fees and increased costs. The pricing mechanism of all gold is opaque, and the available gold prices are all gold.
