Mint Of The United States At San Francisco Ingots - Missing Link Part II

Recently I acquired a Type II oval hallmark ingot that makes a significant contribution to the scenario I presented in the last post about the production timeline represented by the three ingots pictured below.

I was originally looking to fill the gap between the mid to late 1940's and the early to mid 1950's. I believe that the last 5 oz class serial numbered ingots produced at the Mint Of The United States At San Francisco are the Type I oval hallmark, small font in 999.5 fineness. That would transition perfectly to the Type I oval hallmark, 999.5 fineness on the left of the picture below. I then supposed that the Type II oval hallmark ingot in the center, filled the gap in the production timeline up to the 1959 dated round hallmark.

The recently acquired Type II oval hallmark ingot in the center below lends itself to this argument by bearing the exact same lot number stamping as the 1959 dated round hallmark ingot on the right.






Bits and pieces continue to fall together, hopefully some day I will have the entire story to tell!

  1. Ken: A friend of mine has a bar that is identical to yours shown on the right. It weighs 6.707 ounces. How do we go about learning more about what it is and the market value?
