Advice needed please.

I found a tiny shop here in Japan run by and old man. In the shop he has a dusty old display case and inside it he has several Famicom and Sega games.
all new and boxed. They all have the original prices on them. I asked him if they were really that price and he said he would sell them for half. I then asked how much he would sell them ALL for. He said that if I buy more than 100 I could buy them for about $10us each... but there were only about 20 games in the cabinet. Turns out he has several cases of brand new famicom games in his storage area never touched by human hands.... I will get a full list of all the titles he has tonight. My question however is do you wise experienced people think the resale value of games is much higher than that?
For example there was boxed Mario Golf. Mario USA, Dragonball and Duck Hunt that I didnt even know was available as a solo Cart. I don't remember the sega games off hand because i was too busy peeing my pants at finding them all.
Any advice?

keep in mind that famicom games do not come sealed, many of those titles are uber common even in japan. 10$ isn't a bad deal for complete espeicaly without having to worry about shipping, mario usa for 10$ is definatly a good deal (its mario 2 if you didn't know)

keep in mind also rpgs are dirt dirt common (dragon warrior final fantasy etc etc) unlike in the us, but still I'd jump at 10$ a piece since I collect famicom games.

I got the list today. There are 151 different Famcicom titles and 30 Mega Drive games. He has quantities of even 50 of some games. All new in boxes...
Now I have the fun of translating it and figuring out what is actually valuable.

*sigh*

Thanks for the advice
