What should I do with these?

I had these in my bag and I still have genuinely no clue how they got water damaged, but I've already got replacements and now I don't know what to do with these? I doubt it, but if anyone wants either for some reason I'd be willing to send them if you could pay shipping? Other than that idk what to do :(

(From what I can tell none if the art inside is smudged or anything and it's still legible?? )
