US Assay Office at San Francisco Silver ingot No.517, Type II Hallmark 100.09oz 999.5 fine
According to our friend Ken Conaway and his thorough research on early silver ingots, "...The Type II oval hallmark appeared around 1946 but is found on very few 5-ounce class ingots as it seems that most ingots being produced in that time frame were in the 25-ounce class range and larger."
