Jacobs (1846-1936) were brothers, merchants, and bankers. Their father, Mark I. Jacobs (1816-1894) was an established merchant in San Francisco who sent them to Tucson, Arizona in 1867 to open a new branch of their retail store. Initally called the M.I. Jacobs and Co., the name was changed to the L.M. Jacobs and Co. following their father's retirement in 1875. Following their arrival to Tucson, the brothers found success in their exchange business; gold coin from San Francisco was exchanged for paper money in Tucson. By 1879 they established the Pima County Bank, the first bank in Tucson. The brothers gave up the mercantile part of the business in 1880 to concentrate on banking. They later became associated with the Cochise County Bank of Tombstone (known before 1882 as the Agency Pima County Bank) and the Arizona National Bank (first called the Santa Cruz Valley Bank). The condition of this Pima County Bank check is well preserved with a small tear in the top right hand corner and browning to the check consistent with age but otherwise shows a well preserved condition. The measurements of this bank note is 3 3/8" x 8 1/8".
