Jeff,

The Log Cabin Club in Yreka, Calif, was established in 1934, and it's still in business at this time. However, to the best of my knowledge card games were only in operation from the late 40's through approximately the late 70's. Large Crown chips would fit the in operation times for both the Yreka and Hawthorne Log Cabin Clubs. I would agree with Allan's assessment of this chip as being Unknown.
