For sales purposes, I think there's a 'grade' point of diminishing returns. The amount spent will not positively affect your sale if its below a certain grade. In fact, in some cases, it confirms the low quality and negatively impacts the sales price. I'm not sure where that point may be. That turnaround point could actually be different for different cards, not sure.
