The PIN thing can be done online at both of my banks.
As for the cash stuff, those are things you may need to do if you’re a shopkeeper, but I can’t imagine a reason why I would do that myself. Banks over here will sometimes charge fees for changing cash.
in the US $2 bills are an icebreaker. There's still a lot of people that don't believe they're real. I also used them as incentives for my kids to go above and beyond with their communal chores. The quarters thing i haven't done personally but i was adjacent to for a club, it was for a game in a booth at an event.
banks here don't charge, as one of their expected roles is to change money in the US.
