Where do I get the last part of the coin on Nancy Drew and the Secret of the Clue Benders Society for DS?

This is not the answer, I just wanted to add more information to my question. I'm in the village and I have 2 parts of the coin, 1 from Sprinkles and 1 from ... (someone else). I have no idea where it can be. Also, when James lets you go into his shed to get the box, where is it?? I never found it. And what is the purpose of the restaurant place? Is there something important I need to find in it?

Got it from the guy's dad. Never mind.
