Note at the end of the article, the chip I show below is actually named (who knows how many of each he made). Although these chips are recarved, they are still some of the most desirous ivories. I think it is more than likely that he had the opera tokens in the Edith Head necklace recarved as the lettering is identical to the lettering on the riverboat chips. That alone adds to the allure (and maybe value) of the chips.
