A friend just returned from a European vacation and brought me a couple of souvenir chips... one of the legs of her trip involved an overnight cruise aboard the "Duke Of Scandinavia" from Newcastle on the northeast coast of England, across the North Sea to Amsterdam... the chips used in the onboard casino were pretty generic - "Bell Casino" hotstamped on several different color chips with an alternating rectangle and diamond mold (I had not seen this chip before). Once in Amsterdam she acquired the more common 5 euro chip from Holland Casino. Not sure about the gambling, but the food was said to be quite good on this boat.
