I picked up this pair of dice today but I dont usually collect dice and dont know much about them. I have three pictures of the one pair from Caesars Palace. Can someone help me with a few questions? I was told they were from the 70's or early 80's and that the logo picture is not common. They have matching numbers and are not cancelled. Can someone tell me when they are from and if they are common or not? Any help would be appreciated.
