I have given six Numismatic Theater / Money Talks (name change) at ANA conventions. Are you an ANA member? Check and stay current with money.org. The deadlines for proposals is kept up to date there. When the World’s Fair of Money was held in Rosemont in 2011, 2013, 2014, and 2015, I was the ONLY speaker who presented all four years.  QDB was three out of four. 

I don't think so. It looks more like machine doubling to me. Just caused by a loose die. Nice coin though! 

Image is too small to be of help.

If you get the smaller one, not too exotic, and away from major cities, a fiver still gets you there. 

I'll take a look if it will help.

Regardless of PL/DPL pricing...the MS-70's sold by RCTV for $4,700 are WAY above FMV. 
However, anybody who can't verify the price is just asking to be separated for their money.  At least they are getting a very nice coin and a good story, even if they are overpaying.  There are scams out there where you lose 80-100% of your money.  Here you're overpaying by about 25-35% or so.

You have a greater familiarity with this series than most people do and, as you are aware, pricing is beyond the control of eBay.

So this weight is obscure, since 25+ weights were meant to be melted down by someone who worked with silver.. not many of these survived.  These end up as center pieces in people's collections.  These rarely come to market.. I mean even the 5-8 oz bars are hitting almost 20k alone

The San Francisco Branch Mint was returning gold bars to her customers right from the start in April of 1854. For the year, only a handful of these returned bars were refined, most were unparted with no attempt being made to separate the silver from the native gold. I know that the Philadelphia Mint had returned gold bars poured from California gold to her customers in 1853. They were reportedly stamped with their weight and fineness and also carried a glued on paper label with them, or sort of a memorandum.  Beginning in 1856, the San Francisco Mint also paid out some silver bars to her depositors. 
If the S.S. Central America had sunk in 1856, there would have been a decent chance that she carried some San Francisco Branch Mint gold bars in her treasure hold. In 1857, the S.F.B.M. had returned zero gold bars to her customers.
Letter from the Archives
Mint of the United States Philadelphia November 5, 1853 Sir: I forward to you on the 3rd instant, by Adams & Co. Express, a Box containing the stamps for the gold bars-letters, and figures, and a large set of figures for the Melter & Refiner, which I hope will reach you in good order and in time for your contemplated commencement of operations on the 1st of February next.
I am respectfully Yours, (signed) James Ross Snowden Director.

DWL my late grandmother and father were both born in San Francisco....  
 
 
   
     

They are kidding on that estimate, right? I used to own this little 49.04 Tr. Oz. New York Assay Office bar dated 1950 in my birth year set and it was not worth multiples of melt!
 
 

@RWB:
In my mind's eye I thought a silver bar like those bearing the Engelhard hallmark were standard size and filed down after production.  But this has an odd weight making it unique. Henceforth, I am going refer to these bars, as "outgots," as they are custom-made pours, with varying dimensions. I assume the year the Mint began fabrication of these bars (1857) and the sinking of the S.S. CENTRAL AMERICA, which carried a boatload of such bars, many from hitherto unknown assayers, was entirely coincidental.
  🤔 

The Mints routinely made precious metal bars from 1857 forward. These were sold to dental fabricators, silversmiths and other trades who wanted small quantities of metal of known purity. To be accurate these are NOT Ingots - they are "fine metal bars." (An "ingot" is a specific dimension metal bar once used to roll out strips for cutting blanks.)

Coming up on the auction block at the Long Beach Show, September 30, 2022, is the above item, No. 161, 27.88 ozs. (Type 3 hallmark) as offered by auction. or auctions.vegascoindealer.com
The current bid (as of post time) is $27,500, with estimates given ranging from $26K-$44K.
I do not collect these. In point of fact, I was unaware the U.S. Mint, or any of its branches "minted" these.  I assume a slab might not be entirely out of the question.  My only question is how does one "grade" these? Obviously, a pristine bar would be collector worthy, but who or what do bar collectors consult for guidance. Just curious. [Sorry I cannot provide a link; I have only been a collector for 50 years.]   
 

...usually not graded...unaltered probably a better way to go....

@zadok.  To the best of my knowledge the last coin club in my hometown ended when it's founder, a man named Glenn died in 1982. There could be some private affair but if so I am not in their loop.  A fellow named Brian is one of the sons of Glenn.  He has been a vest pocket dealer for as long as I have known him.  We speak at least monthly so I would be surprised if he wouldn't have mentioned a coin club to me.
Sadly, due to a health crisis in December I have been  forced to isolate from the public for the last 4 months.  Otherwise I would have liked to attend one of their meetings.  They meet at a Perkin's the last Friday of each month and I have an open invitation.  If nothing else, I am hoping to find people there who would be interested in some of my many Numismatic books.  Neither the Library or the Hospital Aux. group will take them.  However at this time most of their members focus on buying junk silver.  James

No relation at all. Not the same subject or question.
The thread was about a bag of Kennedy halves that NGC "processed" into something they weren't.

My examination was conducted with complete objectivity several years before the TPG ever saw the original bag. The opinion rendered was based on all the facts available, and only on facts. The modest compensation for the work was agreed to in advance, and was not predicated on any outcome. I have no knowledge about what happened after the report was delivered, or who might or might not have read it.
[I'll add that I don't do "directed opinion" requests. The total of available facts tell the story. A brief example is the article "KING OF MORGAN DOLLARS REVISITED" (2006). ]

No!  Stop it!

Give me a break with "nice information" or "an appreciation for our coin heritage... and the very worst thing I thought I would ever have the great misfortune of seeing in print:  
".... overpaying isn't the worst thing in the world."
ARE YOU MESHUGGAH ?
Have not you ever heard of "price goughing"?  IT IS A CRIME!
I don't care about this giving a hobby hobbling along a shot in the arm by any means necessary. Not by hook or crook!  Only fair and square.  Prevailing FMV, whatever.  I couldn't care less about the costs related to running the infomercial. (Matter of fact, they're way to-o-o long to begin with.)  Long after I am gone, I would like the piece of knowing the hobby is robust and above-board in its dealings with the public.
The snake oil salesman and shysters can find something else to do. I don't ever want to hear that the hobby I spent practically my whole life in, stooped to the level of the various Public Administrators of the City of New York: those public servants charged with the responsibility of seeing to it any of a decedent's survivors are diligently tracked down to the four corners of the earth to insure equitable distribution of all their personal possessions and property, only to skip the investigative stage to line their pockets. 
 

Alright, okay... the Double-Eagle I bestow upon you will be one of my choice. I give you my word it will not be the '30-S lowball. 🤣

Or, you could try to learn from the experience and see where your grading skills need improving.

That's not true. There is no reason they would ever do that. Be careful of what you say about our host. We are only guest of this site. The words/terms you have used in this thread tell me you have much to learn about grading. Grading is an art and a science that takes many years to learn. 
I have had about a thousand coins graded over the years and use the services as a learning tool. I study the coins that come back different than what I thought they would grade. Most of the time that study teaches me why the coin received the grade it did. 

I've done a bunch from local clubs to national shows. They are always fun to do, and I never had a negative experience. The most persistent problem was lack of time for questions. Part of this might come from having a living author present; but participants have also mentioned that they like not being "sold to" by people with a profit agenda who might give slanted replies. In some instances I've been asked to tailor a previous presentation for a different audience at a future event.
The most important factor is keeping the show moving forward -- you're telling a story and any good story has a beginning, middle and end. (This applies to coin books, too. I recently read a book that was so jumbled that it was difficult to understand what the author was trying to communicate.)
I also end by offering to aid writers, club newsletter editors, and people researching specific topics. This helps me share what I've learned with others and possibly improve future information presentations. It's also led to contacts around the world - and occasional opening of U.S. archive materials to countries whose own archives are incomplete.

...usually the "big" presentations etc r by by invites...smaller regional n local shows combination of invites or knowing persons in clubs or special interest groups...n in some areas i.e. community colleges ask local individuals to make presentations on the hobby or in ur area of interest investment opportunities, some local attorney organizations invite to get current perspectives or trends...
