As I have discussed before, the Type II oval hallmark first appears in 1952. By virtue of receipts held in my collection, we know that it was used in addition to the round dated hallmarks as late as 1958. Very few examples exist in the 5 oz class as most are significantly larger in the 20 oz plus range. In this post we will look at unique 5 oz class examples.
The first Mint Of The United States At San Francisco Type II oval hallmark ingot represents the most common 5 oz class presentation of those I have found to date which now totals eleven. In this series, none have serial numbers and only two of the eleven have weight stamping.
The next Mint Of The United States At San Francisco Type II oval hallmark ingot is unique because the hallmark and fineness have been applied to what would normally be the reverse of the ingot. Compare it to the example above.
One of the two Mint Of The United States At San Francisco Type II oval hallmark ingots that I have found to date in the 5 oz class with weight stamping.
And in the last photo of this post, an example from the series of generally larger ingots that are all of 999.75 fineness and include numbers. Only two examples out of some thirty-five that I have found to date are in the 5 oz range; #217 is 5.23 ozs.
