Do banks still carry half dollars?

Excuse me, could you please clarify something for me? I've been noticing a decline in the frequency of seeing half dollars in circulation, and I'm wondering if banks still actually carry them? I mean, with the rise of digital transactions and the increasing popularity of other denominations, does it still make sense for banks to keep half dollars on hand? Are there still customers who demand them, or have they mostly fallen out of favor? I'd appreciate any insight you could provide on this matter.
