PCGS likely wont grade these. ICG is your best bet. I don't know if I would have the Satori authenticated, but the BTCC perhaps.
I wouldn't waste money grading them, but to each their own. I know some people like to have their collection in slabs and have storage methods setup to accommodate these holders. As far as resale or authentication goes though, I doubt you'd get your money back. You never know though. Mostly I would say that it's your collectible in your collection, so do you want to see it in a graded slab, or do you like it in it's more original clothes. In the end that's really all that matters. If you aren't planning on keeping it though, like I said, I doubt you'd recover the funds you spend grading it, and if it came back with a low grade it might even hurt it's value.
Noted. I'm planning on keeping both chips for the foreseeable future, so I think I'll send them for grading. It's more of a personal preference, as I like to see all of my collectibles in pristine condition. I already have a graded Moonbits poker chip, so grading the other ones would make my collection look much nicer.
I'd like to thank everyone for your advice. It's been of great help to me.
