Mine is simple.
I say that I own a vending machine business and I accumulate them. Unfortunately, none of my banks will take the coins in rolls. It has to go loose through the counter. Only once did I have a problem, it came as $998, instead of $1000. No biggie, however, the fact that my banks will not take them in rolls has stopped me from doing this. It is not worth it for me to open at home, carry them, and wait for the coin counter. Believe me, I've looked at other nearby branches and it is the same story, so I gave up.
