What happens in here, stays here! For most people they are really referring to their money. The smart money isn't on the game its on the dice. Dice are one of the items that are often overlooked by auctioneers and auction goers. Don't get caught in that trap yourself. Determined searching through every box lot will often reward you with jewels like these. While the rest of the auction crowd was gambling to make $50 on a $500 purchase, you purchased a box lot with dice in it for $5. Your reward, a $100 pair of dice.
Most of the value comes in the form of the casino's advertising on the dice. Also keep an eye out for oversize Bakelite dice. Paying attention to the minutia can really pay off.
