Greg taught me this foreign phrase, I am not sure of the origin. The phrase “case quarter” apparently is referring to a actual quarter. So if someone says “Can I get a case quarter?” that translates to: “Hey I have two dimes and a nickel and a need a quarter! Can you help me out?” Oh and here is a Pro Tip for anyone that uses this “case quarter” phrase: if you keep repeating it the other person isn’t all of a sudden going to understand what it means!
