Why is the word 'pyès' used to signify 'no one'?

Pyès ( pièce, pièce de monnaie) → piece, a simple piece of coin

When PYÈS means NONE;  It literally means Not even one PIECE, Not even one UNIT

So you would hear in Creole:

Pa gen pyès moun la.
There not even one piece of a person there. (literally)
There's no one there.


Mwen pa gen pyès lajan.
I don't even have one coin. (literally)
I don't have any money.
