Hi Jerry,
I'm not sure if they were used or not but I'd sure think if they weren't at least MADE for Caesars, there'd be a lawsuit for infringement on their logos that's for sure! If they'd attemt to sue Trump over the use of "Palace" in AC they wouldn't let anyone use their logos.
I have a few of the H&C "couch" series and all show normal 'use'. Question I guess is "where were they used"?
The "BUST/WREATH" design roulette mold, I've never seen them 'un-cancelled'. They all have evidence of the gold cancellation stamping on them. Do you have some with no gold 'residue'? These may have been a prototype that Caesars rejected since all the one's I've seen were in 'mint' unused condition except for the removed cancellation stamp.
Used or not, I could use one of the H&C "BUST/WREATH" style chips.....any extras??

Keep the info coming...........
