Buying Gold

Koji arrives at a large international bank to buy gold and protect his savings from changes in the global market.

Koji learns that 24K gold is completely pure, while 18K, 14K, and 10K gold contain stronger metals mixed inside.

Koji chooses a pre-made 100-gram 24K gold bar, and the bank records its weight, purity, and current market value.

The banker asks if Koji prefers gold bullion, certified coins, or another financial product such as foreign exchange trading.

The banker shows yellow, white, rose, green, and black gold, which are created by mixing gold with different metals.

Koji takes the gold bar home in a secure case, feeling confident that his long-term wealth is now well protected.
