The dice came in today and appear (to my very much a novice eye) to be relatively modern. The color seems uniform throughout each die and they're in great shape with only minor scratches.

They have no cancellation marks but do have a Hidden Letter Key (T) on the back side of the center 3 dot. I've been told Hidden Letter Key's weren't really used until the 70s or so.

I think I may need to wait on trading these until the Feb. show where I can have some of you experts look at them.
