Are these Famicom game guides worth anything?

[ZDog]

These are probably worthless, but I'm going to ask anyway; how much are these "Super Mario Bros." and "Doki Doki Panic" game guides are worth? (I should also note that they aren't really in the best of condition; in fact, one of them has tape holding it together .)

[Kitsune Sniper]

They might be worth it to Mario collectors.

I say put them up on eBay in an auction and see how high they go.
