Nope, those are plastic knock-offs made in the 1980's I know they kind of look like a different kind of chip, but it is nothing but cheap plastic from China worth maybe two cents each, if that.
I would hate for someone to buy six bucks worth of chips for $100+++ It really isn't even worth your time to check it out.
Lots of nicer dice style chips for less than this price.
No really, don't look. There is nothing to see here.

PS The case is really nasty dirty with broken hinges and it could be that crack cocaine dust sprinkled inside.
