I
think it's illegal, but when the change on my dresser accumulates to an unmanageable level, I pick out the quarters, hold up a grocery bag to the side of the dresser, and sweep all that crap into a bag and toss it out.
My rationale is that if you added up all those pennies and nickels, you couldn't even use it to cover the cost of having someone else deal with it.
So why should I?
