I bought 2 of the white Pine Club chips(I believe I was in Santa Cruz, Ca...might of been Alameda,Ca though) And the guy I got them from said they were from San Francisco. He was 50-60 years old and said he got them from some of his father's things he was selling. I CAN'T confirm if this story holds water or is truthful. I am only relaying what I was told.....we have all heard these stories though 🤔
I haven't taken much time to look into it. I think unknown is a good ID.
