The Ex-GF was just in the supermarket. (This is a big chain, not a mom-and-pop.) The woman ahead of her in the check-out line wanted to pay her bills with a few rolls of nickels. The supermarket’s position was that they would not accept payment of this sort. The Ex-GF, who can be a bit combative at times, butted in and noted that nickels qualify as legal tender.

Question… is it even legal to refuse to accept payment for goods and services received in United States currency? (I imagine it would be awfully hard for most websites to accept currency. I also think of times when I was in South America and merchants displayed a strong preference for the greenback over the domestic paper.)
