I know this is about the US penny, but from a UK perspective I think it'd be much more useful to kill the two pence piece. Those coins are massive and, in my experience, never used except to put in those charity buckets. One pennies, however small their monetary value, at least help you make up odd prices, but twos are always just too much to make up a £2.47 bus fare.
Most likely both the 1p and 2p would go and prices would be rounded to the nearest 5p (so you wouldn’t need a penny to make up the odd price). But the UK govt already said they’re not doing this.
