I have an unusual chip with a white and blue swirl design. When it's sitting on the table and you give it a casual glance it looks like the chips on the top of the photo. The type and denom are all but invisible. The top front and backs are a straight scan. This is how they really look. If you aim them toward a bright light you can read the inscriptions. The bottom photos, front and back, were shot with a camera at a glare angle. I collect odd stuff, so this is right down my alley. I have not seen anything quite like this before. My question is, where exactly is this chip from? Aix les Bains is in France near Switzerland and the only other Casino Kursaal I'm aware of is in Belgium. I'm confused. Any idea as to how old the chip is?
