Nice finds, John!

You probably already know this, but...

Have you 'sniffed' your Caesars Tahoe dice? They look like they might be suffering from "vinegar syndrome"...if that's the case, make sure to segregate them from your other dice to reduce the risk of infection.

If they DO smell vinegar-y, the best thing to do is to put them in one of the dice tubes that casinos often use, when they sell their dice. There's no cure for infected dice , but you don't want to infect your healthy dice.
