I don't know of any Reno casinos that use chips valued in Canadian dollars. Some casinos have used special NCV chips to make it easy to give players an extra good exchange rate and guarantee they play that money at least once. But the chips are valued at American money at the tables.

When the Sands was doing this, for $100 Canadian, you'd get $70 of these NCV chips. If you then took your $70 in chips to the cage, they'd give you only $67. But when you play them they'd pay you your winnings in regular chips.

I don't know what they do now, but the "Canadian" chips are gone.
