It was that way at Metilista. Most casinos had either dollar denominated chips or Ruble chips. I know that at many places you had to convert to rubles to get the chips and then convert back to get your money back. I always figured that they probably took a little profit each way on the conversion but never bothered to cacluate it. Metilista was the only one I can remember that had the dollar denominated chips but sold them in rubles. They may have just taken over the casino and didn't have their own chips yet - I am not sure of the reason. Normally if you are getting 25 and 100 or larger chips from Russia they are in rubles. Standard denominations 1, 2.5 and 5 are in dollars.
