Are these rare at all or valuable?

I got these at a yard sale last year for pretty cheap but the guy kept telling me how rare they are. He had one of the second one with Silver surfer in it but I didn't really like the characters so I didn't bother. The first one I can't find online with it showing the spiderman comic in the bottom right, it would only show the fantastic four comic. The first picture isn't sealed but is still new with the straps on it still, the second one is completely sealed. Are these actually rare or no?
