Rulau's U.S. Tokens book says, "Bentley C. Bibb and H. P. Robbins formed a partnership to manufacture stoves in 1851. It was Bibb & Robbins 1851-1855, Bibb & Co. 1855-1877, Bibb & Son 1877-1889, and B. C. Bibb Stove Co. 1889-1918 or later. Bentley C. Bibb died June 23, 1894, aged 79. From 1851 until 1907 or later its location was the same - 39-41 Light St. (renumbered 107-109 in 1886)." He lists the date as (1889) meaning that date or later. He shows both brass and copper varieties with a valuation of $5 each in Very Fine.
