The last-ever penny will be minted today in Philadelphia

I'd say screw it, get rid of nickles and dimes as well. Quarters can stay, for now.

It's a complete waste of money and time continuing to mint such low-value currency. It can't be used for just about anything.

Unfortunately, I do see the problem with part of this. For a handful of items where it does matter, it will force people to use cards more if they want to avoid rounding. And the card providers already have a choke-hold on retailers, and the whole thing is basically a scheme that funnels money from the poor to the wealthy via interest and fees on the consumer, interchange fees, and rewards programs.

I know you're referencing more than pennies, but to speak to pennies, I find the current rounding noise in the US to be weird. Likely, it's just more of the media, talking heads, and youtube personalities trying to turn a nothing into something, story.

Back when we did it in Canada, I don't recall a single person I knew concerned about penny rounding. Everyone was sick of pennies. No one cared. Everyone was happy. And the math seems fair enough:

Basically, if something is $1.01 or $1.02, you round down. If it's $1.03 or $1.04, you round up. Rounding is to be applied after all taxes are paid, etc.

Of course, there was also central guidance and, well, everyone just followed it. It's called "having a society".

People blathering on about stores fixing the rounding are morons, there's no way to do so if you buy more than one item. No one gets ripped off with the above method. In the end, it just works out.

And really, who cares?! It's a penny.

> Basically, if something is $1.01 or $1.02, you round down. If it's $1.03 or $1.04, you round up.

So everything's going to be $1.03 or $1.04. Not sure why you think retailers (or any sellers) would ever, ever, ever let this play into customers' advantage.

But apparently pointing out that obvious truth makes me a "moron," because you can think of some clever ways to get around it that retailers surely won't work around.

Are we pretending that nobody has ever tried phasing out smaller denomination currency, and that we don’t have a vast body of actual case studies to draw from? Why are we running thought experiments at all?

Americans like to pretend that history and the experience of the rest of the world doesn't exist and that things that large numbers of other countries have done successfully (and which even the US has done in the past, in this case, as the half-penny, after all, was phase out a long time ago) are impossible to do successfully.

Sales taxes as they are known in the US were largely introduced in the 20th century. The half-penny was phased out in the mid-19th century.

The legal structure of sales taxes in the US present some unique challenges that simply don't exist as problems that needed to be solved in other countries. These problems can't be legislated away because the authority to do so is highly decentralized. Pretending that these problems don't exist because they don't exist elsewhere is not helpful.

This is very much a case of the Mencken quote that for every complex problem there is a solution that is simple, obvious, and wrong.
