The pin as is stated in the book "In 1904 after leading the national league in batting for the third time. Honus Wagner probably could have sold anything including Insurance as he proved by appearing on a pinback for the Commercial Oldest Accident Company. Pin is 1" in diameter. So it probably dates to 1904.
