I would recommend finding a copy of Larry Eastman's book on Ca. chips. He shows pictures in black & white with over 7,000 listings.
I do a Ca. book each year for the convention and this year have separated the card rooms from the Ca. Indians. My book is done in excel and shows Card room, city, color mold, notes, and what I think they are worth in average to new condition. I should have a color book ready the first of the year. Also will try & black & white if the pictures are readable. armin
