Found 100 cancelled Casino Dice on eBay. 100 Frontier hotel Casino Dice Used In Real Play Las Vegas $24.95 (Free Shipping) http://r.ebay.com/He4ZwW Almost all the dice are usable good practice dice with sharp edges and good corners. I found only 2 bad dice in the whole batch with bad corners and chipped edges. They all have the circular cancellation stamp on the "4" side of the each die. Some triple sets and double sets with matching serial numbers.
