What is the significance of the coinage system in John Wick's world?

In the world of John Wick, the coinage system plays a significant role in its criminal underworld. The use of gold coins as currency is a form of secret currency used among the criminal organization known as The High Table. These coins are not used as regular currency, but rather as a form of currency used specifically within the criminal underworld.

One of the main reasons why the coinage system is so significant is that it represents a form of trust and respect within the criminal community. When someone is given a gold coin, it represents a debt owed or a favor owed to the person who gave them the coin. It also represents the trust and respect that the person has earned within the criminal community.

Another reason why the coinage system is significant is that it helps to maintain order within the criminal underworld. Because the coins are not widely recognized as a form of currency, it allows The High Table to maintain control over the criminal organizations and enforce their rules without interference from law enforcement.
