secret: cutco scissors? 
And those coinstar machines are convenient but last i checked they took like 14% and really, it is kinda fun to count and roll a mountain of change with someone.  My grandpa has this giant "red ape" bank that has to be well over a hundred and fifty pounds when it's full.  Every few years it gets full and he counts it with me.  the last haul was $600 

  it's always fun!
