Gift card amount!?

So my friend at work also works at a shoe store and has gotten me a pair of boots and my daughter a pair of boots with her discount (half price!!) I did pay for them. But it’s so nice of her and she even brought them to me. I want to get her and her fiancé a coffee gift card. How much is ok? 10 or 20? I thought I could do either 5 each or 10 each. Thanks!
