It's worth differentiating between no cash value chips and non denom since the terms get mixed up.
Non denoms add flexibility since you can use it for anything you like.
NCV chips might actually have denoms on them, but are used for tournaments and you can't cash them in.
So all the WSOP ME chips are NCV, even though they have all got denoms on.
I suppose that any non denom would have to be NCV, since you wouldn't know what it was worth
