Are shillings still used?

Excuse me, I'm a bit curious about the usage of shillings these days. I understand that they were once widely used as a form of currency, but are shillings still in circulation today? I've heard they've been phased out in many places, but I'm not entirely sure. Could you clarify for me whether shillings are still being used as a means of exchange, and if so, in what contexts? I'm genuinely interested in the current status of shillings in the global financial landscape.
