The last-ever penny will be minted today in Philadelphia

Honestly nickels and dimes, and maybe even quarters, should go too. It's ridiculous that we don't have $1 and $2 coins in widespread circulation in the US (we have a $1 coin but nobody uses it).

I'd mourn the loss of the quarter. I use those quite often.

> (we have a $1 coin but nobody uses it)

Because they keep designing it in the stupidest way, making it easy to confuse with a quarter. I don't know why they do that.

That said, I do prefer paper $1 bills over coins. Paper is lighter and easier to carry. But I'd only slightly grumble if we replaced it with a reasonable coin.

It's a completely different color than a quarter.

That doesn't help if you're in dim lighting or have vision problems.

If you have vision problems, US currency is totally unfriendly to you. Unlike other countries, which have bills of different sizes, all the US currency bills are the same size, so getting change as a blind person is basically relying on the honesty of whoever is behind the counter.
