These are beautiful Antique chips Roy and thanks for sharing them. The two on the left are Seymour coded and the two on the right are not. The chip pictured bottom right I would be afraid to even guess, but the chip pictured top right bears a striking resemblance to the Indian Head or Buffalo nickel. Let me share this with you and I will let you draw your own conclusions. The American Indian Head nickel was designed by artist sculptor James Earle Fraser and was minted from 1913 until 1938. Fraser was born November 4, 1876 and he died October 11, 1953. This is a quote from Wikipedia, "Fraser was exposed to the frontier life and Native Americans, who were being pushed ever further west or confined to Indian reservations. These early memories were expressed in his work, such as End of the Trail and the Indian Head (Buffalo) nickel.
Fraser began carving figures from pieces of limestone scavenged from a stone quarry close to his home near Mitchell, South Dakota in early life. After it became apparent to the family that he was serious about pursuing sculpture as a career Fraser began working as an assistant to sculptor Richard Bock and attending classes at the Art Institute of Chicago at age 14."
So Fraser, the aspiring artist left home at the age of 14 in 1890 to attend the Art Institute of Chicago, 111 S Michigan Avenue. In 1895 the Samuel Nafew Company Company, 167 Dearborn Street just four blocks away was making poker chips. Draw your own conclusions but the time line is right, the resemblance is uncanny, and the proximity of the locations is undenialble.
I love the Antique chips because each one is a piece of American Art and History, and chips like this one are the Holy Grail for Antique Chip Collectors. Thanks again for sharing them Roy.
