Non-cash transactions can still be denominated in cents. Existing pennies will remain legal tender, and it would take quite some time to exhaust those. The transition should be pretty painless. About time really; the time to stop minting these came years ago.
Let’s hope it’s enough planchets to avoid creating an end of the series rarity. All we need is another mint run lottery, like the privy mark nonsense. I’ve spent a small fortune on a one a year cent set from 1793 to date. I’ve got four large cents to go plus a 2025, which will be in a silver coin Proof set. I don’t want to pay a high price to a flipper for a piece of “modern junk.”
I hope so, too, although I imagine the mint's marketing arm will find overpriced NIFC "commemorative" cents (struck on a real copper planchet!) very hard to resist.
