Round, yellow you rap them on a stone and they go ding

In Once Upon a Time in the West, Cheyenne is telling Jill that there is a whole heap of whys, and then he says

"Round, yellow, you know the kind, you rap them around a stone and they go ding..." and she replies that she knows the kind.

What are they talking about?

Best Answer

Sources I've found for the quote state that it's actually:

"Round. Yellow. You know the kind. You wrap/rap ‘em on a stone and they go ‘ding!”

And I'm guessing that the homophones "rap" and "wrap" are confused in this example... it's a common mistake.

So, if that's the case, I'm guessing that he's talking about gold coins, or generally money. So the "whole heap of whys" is a pile of gold coins.
