U.S. Assay Office New York Silver Ingots- Part VI

Recently able to add yet another 40 oz class U.S. Assay Office New York silver ingot to my collection, the 1951 example third from left. These are awesome ingots to handle, like a small silver brick; surprisingly heavy for the size.

Updated from my last U.S. Assay Office New York post, the 40 oz class silver ingots that I have come across in my research, represent the widest range of dates in any of the three common sizes; 40 oz, 100 oz and 1,000 oz. In the 40 oz class, I have now come across the following dates; 1908, 1928, 1940, 1946, 1949, 1951, 1952, 1954 and 1957. The examples pictured below are dated 1928, 1949, 1951 and 1957; four of the nine dates are covered so far. 

Another neat thing about the 1951 ingot is finding a U.S. Assay Office New York silver ingot that is exactly as old as I am!

Mint Of The United States At San Francisco Type I Ingots - Part XIII - More Seeing Double

My last post covered two ingots of the very same type and series with identical numbers; as noted that situation is the only I know of. Identical numbers between different types and series are extremely rare but not one of a kind.

There are a few others in my registry but the duplicate numbers that I have in my collection follow:

Type I oval hallmark, curved stem nines, one in 999.75 and the other in 999.5, both #5


Type I oval hallmark, curved stem nines, one in 999.75 and the other in 999.5, both #946


Type I oval hallmark, curved stem nines, one in 999.75 and the other in 999.5, both #1267 and a one of a kind over sized Type II oval hallmark (only used on reverse of plates) all with #1267


Type I oval hallmark unique 20.04 oz and 1956 dated round hallmark, both #1268

Mint Of The United States At San Francisco Type I Ingots Part XII - Seeing Double

In almost eight years of collecting and over four years of seriously studying Mint Of The United States At San Francisco silver ingots, I have been amazed at the lack of numerical duplication within any given type and series...........until today. 

Type I oval hallmark, medium font, curved stem nines in 999.5 fineness and both #1257.



My initial reaction to this find was to closely examine both ingots to determine if one was possibly fake but after lengthy inspection I see nothing in either to question authenticity. Just another first.

Mint Of The United States At San Francisco silver ingot numbering continues to baffle me; last year I created a spreadsheet to track the serial numbers of all ingots in my registry, and overall there is a noticeable lack of duplication between the various series. As yet, the explanation remains a mystery; surely all of the ingots that were melted over the years would not have all been different serial numbers. Why then, within the remaining ingots in circulation that I have been able to find, is there only a handful of numerical duplication between different series.

I will post all of the other numerical duplicates in my collection in an upcoming post.
