Learn Italian: Avete spiccioli per il caffè? No, non ce li abbiamo. - Do you guys have coins for the coffee? No, we don't have them.

Both mean "we don't have them," but in spoken Italian, people often use the verb averci instead of just avere when replacing a possessed object with a pronoun. It adds a slight emphasis and sounds much more natural in everyday casual conversation.

Where does the ce come from in the answer?

The particle ci in the verb averci changes to ce whenever it is placed right before a direct object pronoun like lo, la, li, or le. Because we are using li to say "them", the ci becomes ce, giving us ce li abbiamo.

What exactly does the li refer to here?

It refers to spiccioli (coins or loose change). Since spiccioli is a masculine plural noun, we use the masculine plural direct object pronoun li to mean "them".

Why is there no article before spiccioli in the question?

Just like in English, you can often drop the article in Italian when asking about an unspecified, general quantity of something in the plural. You could also say degli spiccioli to mean "some coins", but leaving the article out entirely is very common here.
