A while ago I posted a wanted post for the Caesars Republic $2.50 chip. Several responses indicated that the casino did not have such a chip. I just received an email from Doug Johnson confirming that nobody at the casino has seen or heard of such a chip. But, there is a Caesars Republic $2.50 chip shown in the Chip Guide. That must be where I saw it. Here's a link to the Caesars Republic chips.
