I grew up in Illinois ("Land of Lincoln") and it was one of the only states where you could pay toll with the penny, because Lincoln was such a powerful symbol. I guess that got killed off in 2017, however. (You can't use any coins now, it seems.)
(While researching this comment, I found it hilarious that IDOT had a COVID-19-related unpaid toll relief program, but they accidentally sent people $0.01 invoices because of how they "leveraged an existing system" to generate invoices. Another use for your penny!)
Put Lincoln on the quarter or even the back side of a dollar coin. Maybe this time make it out of titanium or something similarly like other US coins.
Though, one president might decide to out their own image on the coins.
It'll be weird in Canada when we replace the queen on our coinage...
Also the japanese yen is an entire currency were each unit is a cent.
The problem is that eventually if your solution is to just throw out low value currency your just gonna have to throw out more because inflation.
The proper tool is to rebase your currency once you have accumulated enough inflation through numerous decades.
So stealing same thing today could be felony, but would have only been a misdemeanor when the law was written. So re-basing also helps ensures certain statues and laws remain just. You could argue that law makers should go through old laws or account for inflation to start with, but sadly that is not the reality. Tons of laws get written with fixed monetary units.

Now we still have here and there monetary values given in francs (next to euros). I guess this must be a legal thing but come on, it is time to really move ahead and not keep backward compatibility forever here as well.
An interesting denomination was in Poland where the money was denominated by 1:10000
After long enough the old stuff is pretty much out of general circulation, but banks could still exchange for instance to the newer currency.
Anecdotally (as in I might be wrong :) I remember hearing at the time the 5c piece was phased out it was worth less than when the 1/2c pieces were originally released. NB I have put zero effort into thinking if that makes sense or is true. (edit - confirmed)
[ Edit ] - We also made every other coin smaller. It's always startling to get an Australian 50c coin - even though it's the same size as ours used to be. Our's is now smaller than the AU 20c.

In Canada as mentioned already in the comments we phased out the penny no more made after February 4, 2013.
But many business still today (Oct 2020) have items with prices ending in penny amounts. If you pay with cash it's rounded up or down but if you pay with debit, credit, or cheque the penny amount is used. Stupid because there's no incentive (ha pun!) for businesses to change (double pun!).
Half cents coins were minted until 1857. When they were phased out they were worth the equivalent of 58 cents in 2020 dollars.
Australia got rid of theirs in 1992.
Whenever I go to the US I try as hard as I can to always drop them in the take-a-penny-leave-a-penny-tray lest my pockets tear from the bulk.
Such as when traveling by air or making expensive purchases. There's nothing so satisfying as plunking down a sack of pennies when purchasing stuff and saying "just let me know if it's not enough."
The above is sarcasm. I hate pennies. They are pretty much useless these days. The only joy I get from them is when someone annoys me, I can throw them at the person.
They are so useless, in fact, that it actually costs nearly twice the value of a penny ($0.0183)[0] to mint one.
That said, I'd really like it if larger denomination coins ($1/5/10) were common in the US as they are in the EU. Generally coins with value more than $0.25 aren't used (yes, $0.50 and $1 coins exist, but are rarely used/distributed).

Someone is making a lot of money from the status quo, and they will fight very hard to keep it.
While they're at it they could bring the notes into the 20th century by making them distinguishable from a distance and less easily damaged. If you need to distinguish the old notes from the new ones to prevent anyone getting scammed, might as well kill two or three birds with the one stone.
EDIT: And petrol stations would display the prices in sixteenths, but charge a sixteenth more.
If we have to have sub-quarter, i wish it was 12.5 cents instead.
The common pattern is 1, 2, 5, 10, 20, 50, ...
