In the days when unlawful gaming was prevalent, two up and odds and evens were the games of choice for many gamblers.
In odds and evens, all three dice carried the initials H for heads and T for tails. The outcome of the throw of the three dice was as the name implies, either odds or evens.

The three dice in the image and the match boxes are the genuine article. Unfortunately all my 'quids' are gone so these fake dollar bills had to substitute.
