So for example if we're talking about a sealed Super Mario Bros NES black-box variant (Oval SOQ R), which would easily sell ungraded, would you say the difference in fair market value of a graded vs. ungraded copy would be slim enough to where you would suggest just selling them ungraded? I've wondered about this, because I did notice a sealed ungraded copy just recently sell on eBay in June for $13,200. Or would you say if the seller had this one graded it would've most likely sold for thousands more? Some pics for reference on the condition of this copy:
