Extremely rare Whitehead & Hoag pin dating to 1912, from a set of primarily, but not all, members of the Oakland Oaks.  The set is rare enough that it is assumed that the checklist is currently incomplete.  This strong example pictures outfielder Izzy Hoffman, the only example graded by PSA, assessed at the VG-EX 4 level.  Some light foxing is visible at the curl near the very top of the pin, the Whitehead & Hoag ad on the reverse is lightly toned, with some patina and oxidation visible on the metal components.
