The US Assay Offices were founded to function as a place to receive bullion deposits from mining prospectors and the public to then test the purity/refine the precious metal. Once a purity is established the Assay Office would stamp their seal of approval so the end receiver knew the ingot was true to its purity and verified.
The New York Assay Office was founded in 1854 and closed in 1982. What is unique about this particular ingot is it is likely to have been created do to someone wanting a true "good delivery bar" AKA what is known as a COMEX bar today. In 1951 this was a very rare and expensive task to take delivery of the true metal.
What is unique about the surviving examples of US Assay Office hallmarked ingots is it is under Title 15, Chapter 8 of the United States Legal Code also known as the "National Stamping Act" makes it illegal to stamp any good with the words "United States Assay" as only a true US Assay Office can legally make this stamp / hallmark. This shows how serious the US Government took these ingots at the time and why it is so rare to find a true Gov Issued US Assay Office of New York Ingot. This well preserved example is a piece of American history from a time when our dollar was sound.
