Top left chip has dark purple ball w/UV centered between the third and fourth stars. Top right chip has a lighter purple ball w/the UV centered on the second r in Harrah*s with the UV extending below the letters in Harrah*s. Bottom chip has a blue ball w/UV extending above the letters in Harrah*s
The "green" ring aroung the chips is also of various shades.
Differences are much more pronounced than indicated by the scan.
I know, I know.....too much time on my hands.....
