You have to do it like an old lady. First you hand over the 50 cents. Then you wait for the cashier to acknowledge that fifty cents is pretty fucking far from 10.50. When they say you’re ten short, then you pass the 20.
They tell you the total before you start paying, don’t they?
They say it’s 10.50
If you give them a 20, they’ll start giving back 9.50 before you can even attempt to do the exact coin exchange.
If instead you give the 0.50 first, they can’t start giving change before you’ve presented the rest of the cash.
That’s how you pay 20.50 in order to get 10 back.
It’s something you can do for your own sake to avoid having a pocket full of shrapnel. It’s not necessarily a help for the cashier, and they’ll definitely tell you if they need it. So, please don’t hold up the queue just to give exact or optimal change.

How do I know the total until I’m given it?
The store knows which items are taxed and which ones aren’t.
