Knight of Coins

It is part of what tarot card readers call the "Minor Arcana".

[1] In English-speaking countries, where the games are largely unknown, tarot cards came to be utilized primarily for divinatory purposes.

[3] Coins are considered the "darkest" of the suits in terms of choosing based on appearance and are meant to represent dark-skinned, dark-haired people.

Using this method, a Knight of Coins would be used to represent a young man who is dark of complexion and features.

So, in the case of the Knight of Coins, the card might represent someone who is stubborn or hard-working, serious, or set in their ways.
