1967 Super Hero Stickers (Philadelphia/Marvel?)

Good morning, I have a handful of PSA graded 1967 Super Hero (Stickers) -- which feature an assortment of Marvel characters (Hulk, Thor, Spider-Man, etc).  I believe they were made by Philadelphia; but the PSA slab label doesn't include Philadelphia or Marvel.

I've found it very difficult to look up accurate value/sold info for them.  I love using your site, it would be awesome if you can provide some additional insights.  Let me know, thank you for your consideration.  I included some links below for reference, hope you have a nice weekend.
