I began putting together the ingots presented below in 2011 with the acquisition of #3 and #15 from Old West Gold. Added one from eBay in 2012, a few more in 2013 from Edward A, and finally the last two, #12 and #13 from Rocky Mountain Coin this year.
These Type I oval hallmark, small font with curved stem nines in 999.5 fineness date to the early to mid 1940's. In the last post we looked at a receipt from 1942 for the 999.75 series, I have yet to positively determine which of the two series was produced first.
All of these ingots have maintained their original luster, something that none others in my collection have done. Almost all still bear the pencil marked weight on the reverse. I have read that weighing the ingot and marking the weight in pencil on the reverse was the first step after pouring. And the neatness of hallmark placement, serial number and fineness is among the neatest of all produced at the Mint Of The United States At San Francisco.
This is truly one of the most unique ensembles within my U.S. Government Mint & Assay Office collection of silver ingots.
