Yes, however I admit that I just toss a number out. I can't be certain since there are no completed listings that were "factory sealed" (or I may have miss them). The only ones I found were opened copies.
The sealed values might be higher...or lower. Since there is no actual way to determine this via Ebay, I can't give fair judgement.
However, the opened CIB copies values were taken off averages on Ebay (completed, not "unsold"). I feel you have a great shot at putting them for sale on Ebay for $75 and with free shipping. Eventually a buyer will come and buy the lot from you.
Just checked the NES Classic version...it didn't even sell for $12 CIB! So I can't give a fair value, but seeing it did not even fetch $12, perhaps place it at $10 CIB (opened). $85 for the CIB opened lot.
I would keep it at $75 anyway (all four opened CIB games) with free shipping. Entices a quick sale.
Good luck on the sale!
