Very rare, IMO, and maybe even unique. I've never seen another offered by a dealer, or in a collection. Anyone have one of these? I dont' know that RVL ever used a $100 chip, so I would love to hear if anyone has one of those as well. Royal Viking Line ran their own casinos for a number of years, then contracted Casinos Austria to run things (or vice versa, I don't remember the timeline), so there are chips up to the $25 for each operation. I don't have much of a wet chip collection, but decided to keep on the lookout for RVL since we sailed on that line in the 1980's. I THINK that I have 'em all, but maybe not...
