The last-ever penny will be minted today in Philadelphia

Some interesting complications with rounding I had not heard about before were mentioned here, worth noting I think, especially given the prominence of SNAP in the news lately:

>Four states - Delaware, Connecticut, Michigan and Oregon - as well as numerous cities, including New York, Philadelphia, Miami and Washington, DC, require merchants to provide exact change, according to the National Association of Convenience Stores (NACS).

>In addition, the law covering the federal food assistance program known as SNAP requires that recipients not be charged more than other customers. Since SNAP recipients use a debit card that’s charged the precise amount, if merchants round down prices for cash purchases, they could be opening themselves to legal problems and fines, said Jeff Lenard, spokesperson for NACS.

>“Rounding down on all transactions presents several challenges beyond the loss of an average of 2 cents per transaction,” Lenard said. “We desperately need legislation that allows rounding so retailers can make change for these customers.”

In the Netherlands cash payments get rounded to the nearest 5 cents, in both directions. Card payments are not rounded. If I’m not mistaken, you can still demand exact change according to the law and you’re allowed to pay the exact amount (cents are still legal tender). Most merchants wouldn’t be able to give you exact change, so it depends on the situation what would happen. I’ve never heard of such a situation happening, though.
