I've been at this a long time, pictured is an ensemble of silver ingots from the United States Mint San Francisco spanning the entire run from the early 1930's to 1960. The Mint status was changed to an Assay Office and later silver ingots were produced under that hallmark.I was very fortunate to have access to a lot of opportunity early on, acquiring examples from older collectors that had not seen much interest in their holdings to that point. +/-15 years ago, there was not much competition to buy these. To date, the 5 oz class ingots remain more desirable that larger counterparts and carry a much higher premium.Over the years, research and writings that I have done have contributed to increased popularity and today, any United States Government silver ingot will be offered with a huge premium. Hope everyone enjoys the picture, it was 15 years in the making!

Of the hundreds of United States Government silver ingots in my collection and all of the others that I have seen over the years, finding paperwork to document the delivery of scrap silver to the Mint, the invoice for assay and process and the bar delivery receipt for the same transaction is amazing. Then to put a number of ingots together that are listed on the bar delivery receipt is beyond amazing. I obtained the paperwork completely separate from any of the ingot acquisitions so this is a real prize in my collection.

There are 17 varieties that make up a complete 5 oz class Type Set of Mint Of The United States At San Francisco silver ingots. It has taken years of research and collecting to document this. Mint records are nonexistent as it relates to details of production so precise chronological ordering is based on Lot numbers and a few actual Mint receipts I have assembled.At SILVERINGOTS.COM I present each of these varieties along with information about each of them. Ken
