I recently got an old clay poker chip that has a very similar flower design that is on an ivory chip. I guess you call this a cross over design. My question is.... What time frame would this transition of designs have taken place? In the 1890s, 1880s or possibly earlier? I don't see this yellow chip in Dale Seymour's book. Any help from old chip experts out there is needed. I didn't mean from necessarily old experts. I meant old chips.
