A friend of my brother`s got the chip on the left on a cruise. It seemed diferent from the chip on the right, which I have had for a few years. The $2.50 is a lighter shade of blue and the chip is in very good shape, so it is not faded. The inserts are cleaner also, no splashes. Not much difference until you look at them under a black light. The old chip is only marked on one side and the H&C mark is oriented differently.
Check your chips if you think this makes for different chips. No traders left.
