Hi Charles,

I had originally thought that those chips were not listed in any of the California guides, but Armin Pfaender's and the Staeffler Memorial guides do list them.

I missed it at first because the chips are not listed under "graphics" or the letter "A", but rather under the club name;

This first year that I find them listed is in the 2010 edition of Staeffler's guide. The chips are not in Armin's 2004 edition of his guide nor Eastman's 1998 guide.
