Goodbye, pennies

Yesterday was the last day the US Mint made pennies, completing a 232 year run. I understand why (the cost to produce being three times the face value), but there will always be nostalgia. Given how many transactions these days are cashless, will it actually affect pricing, or will there be an informal “rounding if you pay cash” (in whichever direction) instead? (I suppose I’ll see soon enough given my day job.)

I wonder whether this will make pennies more collectible, for the numismatists who are enthusiastic about them? I have a *lot* of pennies I’ve found in the streets in the last years, not brought to either of the financial institutions I bank at, because one doesn’t do coins (!!!), while the other switched from a free coin counting machine for customers to one that charges some percent (I’m far too cheap to pay for the privilege of having the coins counted, but haven’t yet picked up the paper sleeves needed to roll the coins myself).
