Justin, when you mention 1750-1780, are you
referring to the small, thin Mother-of-Pearl chips
that were produced in China for the European
market? If not, I'm curious as to why the short
time frame.

Please feel free to visit my list below and also
click on to list II. If you do not see what
you're looking for, I can show you much rarer
material.

Are you familiar with Dale Seymour's work:
"Antique Gamblng Chip" - Revised Edition?
