Last month while in Vegas, we had breakfast over at Sunset Station. After which while I was walking around, I noticed that the WIN card Promo was still (or new one?) going on - so I filled out the form, and got it verified at the slot club window. After going to the cashier and paying my $10 I received the WIN Card package with the fifteen chips. I noticed that of the fifteen chips, there were three different colors.
I recall an earlier post that mentioned two colors, yet has anyone else noticed the third?

All three of the chips in the image below were scanned with the same settings (Brightness and Contrast)

What do you think?

Dick
