The Casablanca Casino in Aruba:

The older chip, on the left, is commonly referred to as the light pink chip because of the color in the rectangle around the name, "Casablanca," while the one on the right is called the dark pink variety. On closer inspection, though, there are more differences, and, clearly, the chip was recreated for the second chip order (which possibly occurred during one of the many Hotel name changes that occurred while the Casablanca Casino name remained steady). A closeup view shows:

The difference is easy to see in the letters. Look closely at the "A" and "N" on each. Differences can also be seen in the "C" and "S" on each chip. Look also how the plane intersects with the letters.

At the Hyatt Regency's Copa Cabana Casino in Aruba, there was a difference in the "$" in the mold of the $1 chips:

The $5 credit chips at the Crystal Casino has a minor change:

The word "CREDIT" is bold on one and not bold on the other. I have no idea which is first, or if they were even from different orders.

There are more, but that's enough for now.
