My 1892 U.S. Assay Office New York ingot #10, 8.93 ozs and melt #682, acquired at the Chicago ANA Heritage auction, has quickly become my most prized ingot. The more I research and study it, the more amazing I find it to be.
As with other government ingots from the U.S. Mint Philadelphia and Mint Of The United States At San Francisco that I collect and write about, my research has included searching major auction firm archives including among others, Goldberg, Heritage, Holabird-Kagin and Stack's Bowers, which provide information back to the early 2000's. I also looked at eBay completed listings and obtained information from a number of fellow collectors and dealers; all of this to account for as many U.S. Assay Office New York examples as possible. This research has resulted in seeing many more U.S. Assay Office New York ingots of gold than silver.
Of the U.S. Assay Office New York silver ingots, there are three major categories; 40 oz class, 100 oz class and 1000 oz class. 40 oz class ingots are the most common that I have found. So far I have seen dates ranging from 1908 to the late 1950's. Of these, interestingly, I have seen a total of eight from 1949, all with the same melt #1. 100 oz class ingots are the least common of the three categories with dates from the 1960's and 1980's. 1000 oz class ingots fall in between in commonality with dates from the mid 1950's to the mid 1980's. (Remember that this is only what I have been able to find to date using the research tools above)
Not that those discussed above are not rare, the grand total of all that I have seen is less than thirty five, but the standout U.S. Assay Office New York silver ingots are those that fall outside of these three categories. I know of one 200 oz class ingot dated 1966. I have seen photos of two small 1909 ingots, one is pictured on the flyer in my post last week and I have read an auction listing without photo of a 1919 small ingot. In addition to these standouts, there are the two from my collection, the 1892 above and the 1920 ingot #182, 6.61 ozs and melt #653.
We will look at each of these ingots individually in upcoming posts.
