John,

I was at the St Ignace Kewadin Casino last week. Don't bother stopping as the chips are so old and worn they aren't collectible. While I was there one guy was betting $100 white chips instead of $5 gray (also white with age). Neither the dealer nor the guy knew and he was paid in $5 chips. After 5 hands (him winning 4 of them) they realized. They had to shut down the table and a giant argument ensued. I'm not sure how it was resolved.
