In an engineering class in school and looking for a type of metal that gets charged with coffee?

"charged"? do you mean an electric charge? I suppose one could use coffee as an electrolyte of sorts in a crude battery (actually a cell, but you know what I mean). If a potato can work I guess coffee might to, but it won't be a very good battery. You will need two different metals, I'd try copper and zinc, but I think I've seen instructions for a lemon battery using copper and an iron (steel) nail, which would be easier to find than zinc, though I'd try for zinc myself.

If I was looking for coffee the only thing that would be charged would be a Starbucks gift card. That does have some metal content in its magnetic stripe.

Are you saying that coffee contains some metal?
HUH?
I only know that the FDA permits coffee to contain a small percentage of roaches.
True.
