Origin and Background of the Slang
The slang has two separate origins.
French Origin
The French word fin simply means “end.”
For many years, classic European and silent films displayed FIN on the screen instead of “The End.” This made the word recognizable around the world.
American Slang Origin
The money-related meaning dates back to American slang in the late 19th and early 20th centuries.
A fin became a nickname for a $5 bill, although the exact reason is uncertain. Some historians believe it may relate to the design or historical appearance of early U.S. currency.
Today, the storytelling meaning is far more common online.
