Current Value On old NES Games.?

I recently purchased a box of old NES games at an auction for ten dollars from a video store that went out of business. The games include Mario Bros 1,2,3, Spy Hunter, Eggsplode, Zelda, Hudson's Adventure Island, Bible Adventures, Festers Quest, Galaga, Peek A Boo Poker, Blackjack, Bonks Adventure, Heavy Barrel, Hot Slots, Bee 52, Burgertime, Mermaids of Atlantis, Tiles of Fate, and Bubble Bath Babes. I'm trying to get a current market value if any on these games, any help would be appreciated.
