Sealed NES Game Verification?

[Griking]

So I've been selling off a lot of stuff lately as I've decided that I really don't need as much as I have. Mostly duplicates and stuff but its made me look over a lot of stuff that I haven't really paid much attention to in a while. So in my organizing I came across seven NES games that appear to be new and sealed. I'd like to place them up for sale on eBay however I'm not really 100% positive that they're real seals since I didn't personally purchase them at a retail store. Most of them still have the hangers or price tags on them but I know that doesn't mean anything. I remember back in the day that Funcoland or Gamestop used to reseal these so how do you guys confirm that a game is really new before you list one as such. I'd again really like to sell these but I also don't want to make a fool of myself or screw someone either.

The vast majority of factory sealed NES games have a special line seal along the back. That's the easiest way to tell and along with the period price stickers, should be enough to convince most collectors that what you are selling are legit. Out of curiousity, what games are they?

Pictures would help, I bought SMB3 and Teenage Mutant Ninja Turtles "Factory Sealed" about 10 years ago and an ex of mine decided to open them...but it didn't matter since the cartridges had smudges and TMNT was missing the instructions

I'll try to post pictures later when I get home. The games are Super Mario 3, Legend of Zelda with a Classic Series Band on it, Power Punch II, Where's Waldo, Kirby's Adventure, Championship Pool and Hudson Hawk.

I've posted some pics here.

Sorry if they aren't the best. For some reason my camera has problems with clear close ups.

Btw, the Kirby Adventure game seems to be a French version so I don't know if its worth listing.

At least on the ones I can see it on, that looks like the factory seal to me.

I think that's the Canadian version of Kirby's Adventure, they pop on eBay fairly often. I think they usually go for around $30, maybe higher. If you don't want to list it, PM me.

Those all appear to have the factory sealed line in back and look legit to me.
