The acid will eat the zinc.

I made the mistake of mixing in one stupid token in with some coins I was cleaning. The crap they use to make the token out of stained all the other coins. It was almost like plating process. Couldn't get it off the other coins. I also had a jar of pennies in the soak too long and the zinc from one that I had mixed in with all the other older pennies suddenly turned all of them black. Lesson learned...don't mix metals when using a soak like vinegar.
