I also have several unknown pairs of dice. I have checked The Gaming Table and Jeff Laudeman's books, but there was little or no help.

The dice do have the following initials or letters:

- PC
- CC
- P tm (with a small crown)

I have published some more dice without ID on my website:

Please let me know if any of those dice are familiar to you... Thank you.
