Birmingham Sponsor's Mark by: Yvonne Hammouda-Eyre
Lawrence, providing number "9" in the gold hallmark is facing north-to-south, not east-to-west, the gold sovereign case, is comprised of 9 carat gold and not imported. Without seeing the birmingham hallmark, the date mark could be, 1811, 1861 (capital M), 1886 or 1911.
