I have a lot of similar tickets from the Riviera in Las Vegas plus Harrah's in Lake Tahoe & Reno. Similar coupons/tickets were also used at the Horseshoe Club in Reno and the Royal Casino in Henderson. All of the many variations I have are shown on the ChipGuide under each of the casinos in the OTHER ITEMS category if anyone wants to take a look.

I have a bunch of doubles for many of the tickets and have them listed at the bottom of the common slot card pages on my website if anyone is interested.

Here's links to my Harrah's ticket doubles
