Club Nintendo Codes

I'm not sure if this is the right location for this post, but I'm not sure where else it fits.
I happened upon an extra four code papers for New Super Mario Bros. Wii. I already registered it, so I'm not sure if these codes are valid. When I enter them, I receive the message: "You have already registered this game title."
Does this mean the code is still valid? IIRC, an already used code will give a different message, something along the lines of "this code has already been redeemed", even if that game is already registered with my account.
Can anyone verify if my understanding is correct, and that these codes are still valid?
Also, does anyone know if these have any resale value? If so, where can I sell them?

You can give me one out of the kindness of your heart!

That message means you have registered the game, it will say code has already been redeemed or no longer valid if it has been used. You can sign up a "child" account and register another copy of the game on that account if you need the pts.

As was previously stated you can open up a bunch of accounts under the family account option and then register the codes through those dummy accounts and the points stay accumulated into your main account and then are usable as a whole.
