You’re right - don’t know why I said 1964
I haven’t actually seen the episode, but… surely that’s the joke? She doesn’t actually expect such a machine to exist, she’s just being funny by wondering if such a patently ridiculous thing as a coffee machine that takes 20 dollar bills exists. If they actually showed a coffee machine with a bill reader, sure, but otherwise this seems like the shows titular smart ass being a smart ass.
It’s Joel’s mother - a woman with no discernable sense of humor - who says it. Maybe it should be understood as a joke but it didn’t seem that way to me.
I’m not familiar with this show, I’ve never seen it, or even heard of it, let alone the scene you describe.
Are you certain the date was 1964? Not 65 or 66?
According to this cite, "In 1965, John Greenwick invented the first vending machine that accepted paper bills. "
Is it possible that it wasn’t a mistake, but a deliberate and accurate reference to something that was brand new at the time depicted? And it’s possible that someone encountering it for the first time wouldn’t know if it takes twenties or not.
The current season (fourth) of Mrs. Maisel takes place in 1960, so somewhat sooner.
She’s also a woman with a very tenuous connection to reality.
Unfortunately i was wrong in the other direction - it’s fall of 1960.

The Draughtsman’s Contract did a pretty good job of it.
Interesting.
Noticing a film is in the “wrong place” is often about one’s area of expertise. My ornithologist friends cringe when they hear a New World bird call in a supposed Old World setting, when the rest of us don’t even notice there are birds in the soundtrack at all.
