A bold title for sure but a legitimate question. The issue of fake silver ingots comes up frequently during my presentations to coin clubs and while it is a topic far too big to cover thoroughly in a blog, (Karl Moulton's book is almost 1,000 pages!) I want to touch on it in a few upcoming blog posts.
Articles similar to the one below from the May 1972 edition of The Numismatist, the monthly publication of the American Numismatic Association (ANA), were not uncommon and have left their mark on the mindset of collectors to this day. At the height of the fallout of the exploits of John J. Ford and Gerow Paul Franklin, the general numismatic attitude changed to "guilty first", considering it a fake until proven authentic. Mint Of The United States At San Francisco silver ingots were thrown right into this mix as you can see from the article below.
When I began collecting US Government Mint & Assay Office silver ingots, this attitude still existed towards at least one complete series pictured below from the Mint Of The United States At San Francisco; the Type II series pictured center top row of second photo.
Over a few blog posts we will look at some of my research that authenticates the US Government Mint & Assay Office silver ingots and why the others on these pages are more accurately identified as something other than "fakes".
