Todays coinstar finds and 1 unique find

[Mytoys]

So these are today's finds and 1 very unique finds I'm trying to find out more about what it was once attached to. A Ceasars coin/button it's completely flat on the underneath and did have a glue backing so it was attached to something the closest I could find on that style was the 200 Sega Games but the company never attached any logo buttons to their games. So I am stumped, maybe there's a Caesar buff out there that has the answer.
I added a photo with a dime for size comparison.

Maybe something associated with Caesar's Palace?
