TD Bank around NYC has started to do $50s by default in high-demand locations, obviously so the machine needs refilling less often. One workaround hack is to withdraw a number like $80, to force the transaction into $20s instead. Although I've never yet had a problem spending a $50.

Also, ATMs on casino floors in Vegas dispense $100s.

Interesting that it's a Canadian bank (TD) doing this. I wonder if they're using the same ATM tech in the US as they're using up here.

I've noticed a couple of banks in Canada where, if you ask the ATM for $100, it'll ask you if you want a single $100 bill, two $50 bills, or five $20 bills.

Vegas, baby! Las Vegas ATMs give you $100 bills. That's the only place I've ever seen it, though.

(Maybe Atlantic City, too. I can't remember...)
