Another great auction....OK, you save a hundred bucks on the slab.
The 2x2 holder the chip (in your auction link) is in says -"only 4600 minted...Rare! Uncirculated!"

Then you read the seller's ad...

"The Official U.S. Casino Chip Price Guide has it listed at $60 in almost uncirculated grade (95) and the Colorado Chip & Token Guide, authored by noted expert Ralph Mancinelli, has an official price published at $100 in Uncirculated grade (100). It is estimated that 5,000 were made"

Which official US Casino Chip price guide was he looking at? (not my copy, that's for sure) Estimated 5000 were made? What happened to only 4600 "minted"??? Bit of a contradiction....but he does state that the holder may not match the one in the ad?!?!?
This chip is uncirculated 100....guess that's like a perfect 10. (I have yet to see a "perfect" chip).
At least he's not gouging on the shipping fees
