In the Laudeman book, Jeff makes this comment on a pair of "Ray" dice: "This variant is cancelled with the word "Fun". Harolds had a slogan at the time, "Harolds Club, For Fun".

Hmmmmmm, Jeff has all of the Ray dice priced at $8-$14...EXCEPT for two pairs that have the name on the one side. Those 2 pairs are priced at the next level up ($14-$25), with the comment "Interesting in that the logo is on the one side, which is uncommon for this club."
