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).

We also have a $2 bill that nobody uses for whatever reason.

I never understood the objections to the $1 coin, especially after the redesign to make it more distinct from a quarter. $1 coins are great for buying stuff out of vending machines since you don't have to fight with a dodgy bill acceptor or a mangled bill.

My only real objection I guess, and the reason I don't carry change of any sort, is because it's constantly falling out of my pockets. I'm rather tall, so many seating positions put my knees higher than my waist, which I think contributes to that.

Further, since I don't have enough pockets to have a dedicated change pocket, it's always getting caught up in my keys and/or pocket knife.

Nobody really gave us training on this stuff, do other countries use a coin purse or some such?

Lastly, they're just comparatively heavy.

I just carry cash around in either a clip or a "front pocket wallet" I think they're called, and it seems more convenient all around.
