Even if we stop making pennies and nickels, most merchants will still accept them. So if a merchant tries rounding up to the next dime increment, you can probably force them to take your pennies and nickels. Smart merchants would, just for the value of the metals. (My wife would kill me if I touched her stash of hundreds of thousands of pennies.)

I didn’t see where it said they were being taken out of circulation, only that production would stop, Did I miss something?
