Game Genie Codebooks

[spman]

I recently acquired a huge lot of various stuff, and one of the things that was included was the Game Genie for SNES / Genesis / NES along with the original codebooks that came with it, and all the supplemental codebooks you could mail away for, for all of them. The only thing Game Genie I am aware of being valuable is the top loader adaptor for NES, but I've never seen these mail away codebooks before, they sort of look like newsletters. Does anyone know if they're worth anything? Are there big time Game Genie collectors out there that want them?

These code update sheets aren't worth jack. By the way, which version of the Genesis code book did you find? I've been trying to find scans of the second one. If you are unsure, flip the S section under the table of contents and list the Sonic games shown in your reply.
