We had house guests from the U.S. this weekend. One of their presents for our daughter were some shiny new state quarters from their home state to play with and practise counting. We explained to her that she couldn’t buy things with that money here, only in the “États-Unis”.
When our friends prepared to leave and packed their suitcase, they gave us some cookies they had left over and which our daughter liked a lot. She wanted to buy more, but Daddy explained that they don’t have those cookies here, only in the “États-Unis”.

She: “J’ai l’argent des États-Unis, je peux aller l’acheter chez États-Unis.” (I have money from the U.S., I can go and buy them in the US.)
