bits and bobs

Hey Phyllisstein, WELCOME back! Glad to see you back after a long time away... hey, guys & gals, we've got ourselves at least one South African after all. Who was asking about that a while ago?

I've heard bits and bobs before too. I haven't found it on any of the usual phraseology sites and google didn't turn up anything either. The 'bits' bit is obvious, I suppose, but what is 'bob' in this sense?

Does this have its origins in coinage since both qualify as loose change?

What kind of loose change? Have never heard either used in reference to money. Can you give an example, Phyllisstein?
