How do we carry our caps?

I'm doing an idea thing and trying to decide how the character or even npcs typically carry their caps. A little leather pouch makes the most sense, but that feels too medevil.

Ignoring the fact that most players carry thousands and thousands of caps, how do yall roll play or imagine that caps are carried around? I really want to showcase caps being carried, so anything more than "just pockets" is helpful!
