Mint Of The United States At San Francisco Type II Ingots Part I

Until now I have only written about Type I ingots which make up most of the Government Ingot Collection of Ken Conaway; with this post I introduce and we begin to explore Type II ingots. I have been researching these for some time but mainly as they relate to Type I ingots; recently I took them on as a project of their own.

The Type II oval hallmark series had been the subject of suspicion over the past few years and my first task was to write a paper addressing the various arguments that were being made, challenging the authenticity of the entire series. My paper presented dated examples, documentation of mid 1950's advertising and sales, and US Mint bar delivery receipts along with photos that certify series authenticity. After months of research, my paper was distributed last fall but I will gladly furnish anyone a copy on request. 

First on display, enlarged examples of both Mint Of The United States At San Francisco oval hallmarks; Type I first, followed by Type II: 

Type I

Type II

The earliest date on a Type II oval hallmark ingot that I have found so far is 1952 which places the series logically after the latest records of Type I ingots dated in the mid to late 1940's. In my last Type I post, I noted the rarity of non 5 oz class ingots in that series; the Type II series is just the opposite with 5 oz class examples being the exception.

Presented first and as far as I have been able to determine to date, one of only two Mint Of The United States At San Francisco Type II oval hallmark ingots with serial number and weight, in the 5 oz class, obverse and reverse.

In the next photo, Type II ingot with weight stamping on the obverse;

And in the last two photos, Type II ingots without serial numbers. Neither of these examples are weight stamped which is consistent with all other 5 oz class Type II ingots I have been able to research; if the weight is not on the obverse of these unnumbered examples, it is not included. 

Much more to come on Mint Of The United States At San Francisco Type II oval hallmark ingots.
