I would ordinarily have contacted some of my ivory collecting friends both to alert them to this chip offer and to ask for their opinion on it. [However, our e-mail server is down.] It has a $50 denomination on one side [shown] but $20 on the other. I do not find it in Dale's book. If it is not a "new creation" it is something very special--and even if it is new and not old, it is still very interesting.
