I am totally ignorant when it comes to dice. I do know enough to know that these are matched pairs with the same number. Some are silver stamped and some are gold stamped. The top set is an amber color and there are two blue and two green with different colored stamping. All are drilled about half way. Are these promo dice or canceled table dice? Is there any value to them? I am not in love with them so I will trade for chips or tokens.
