Nice find! Please do consider posting your pics on tokencatalog.com There is a 5¢ token from C. E. Palmer (alone) listed there and in Kappen's CA Tokens book. From a notice in the Ukiah Daily Journal 30 Sep 1910, the Willits correspondent states that "Leech and Palmer have taken the agencies for the San Francisco dailies." That suggests to me that Leech & Palmer had a cigar store with a news counter where they sold magazines, newspapers, etc. in addition to cigars. Oh, BTW, the composition is brass which was typical for tokens of the US.
