Thus far, all of the photos are of counterfeit, or highly suspect, pieces. That does not mean the collection is ALL fake. However, it suggests you should take the collection to a professional numismatist who can help you sort the fakes from real coins. The value is in the authentic coins. Fakes are worthless.
Further, pay the numismatist a fixed fee for their work. Do not sell to them until you have done more research about the authentic coins. The more you know, the better your chances of getting a fair price.

Image is too small to be of help.

Cast bars from any of the mints or New York Assay Office were made individually and marked accordingly. M&R kept them within a range of weights simply by using the same iron molds. The employees were very good at this resulting in only small variations. The bars were raw material for manufacturers as well as bankers. There was no premium on these when made and no known collectors. Many small business users simply melted coins as needed.

I'll take a look if it will help.

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.)

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). ]

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.

I am afraid that is not possible. By your own admission, you date back to B.C., i.e. Before Coins. 🤣

Nose is too big on 1950 and 2023. 
First two are out of focus, others are better.  Now the tough part -- getting light on the face of the coin w/o reflections off the mylar 2x2 windows. (No, using an Apple iFone will not help with Windows....)
 

This might help in the discussion ---or maybe not.
 The US Mint’s definition as mentioned during their annual meetings with resellers and at other times includes anyone that has put aside (“collected”) coins from circulation, or bought any coin-like product direct from the Mint or from any Mint reseller, or from any TV, internet or envelope stuffer promotion, or from newspaper ads. That is: if one saved a state quarter, you were/are a “coin collector.” The result, as we can all tell is a nonsense number – not even an estimate at the old Polo Grounds in NYC.
 A. From about 1855 to 1960 the most basic collectors were those who put aside pocket change, or kept new coins exchanged at friendly banks or merchants. (Until about 1896, people had to have the correct kind of paper currency or coin to exchange. One could not save $20 in silver coins, then take it to a bank and exchange for a double eagle.)
 B. In the 1858-1916 period a meaningful next point might be with the quantity of minor coin proof sets sold per year. Also included were those who wrote to individual mints to purchase new coins at face value. These were purchased by people willing to devote time and extra money toward acquiring special coins. These buyers also recognized that the premium they paid was likely not recoverable in their lifetime. These were coin collectors in the second (or “invested”) level.
 C. The next level – the third – are those buying from coin resellers, auctioneers, or dealers. Here, the investment of time and money were greater than direct US Mint customers, and the variety of coins available (along with associated claims of rarity) was much more intense.
 A side-level from about 1935 to the present depends on precious metal pseudo-coins originally used for emergency hoarding of sovereign-size items. These now extend to anything from Indian jewelers’ counterfeits of small denomination coins for hoarding gold on a small budget, to kilogram and larger imitations, or cute designs intended to attract attention to otherwise identical lumps.
 To reach a realistic estimate of the total number of collectors for any time period, we can add B  and C, then multiply 10-times to get A; then add A+B+C. (A, B, and C all have internal complexities and cross-purchases, so none are ideal estimates.)
 When we run out of B-level product in 1917 we don’t necessarily lose the collector – they likely split between A and C. About this time we also see a rise in merchant-driven popular advertising, especially “treasure in your change” approaches which seems to have created more A collectors. (We’ve seen something similar when comparing ASE and AGE bullion demand before and after Congress’ prohibition on US Mint coin advertising.)

As World Colonial noted, it all comes down to price and availability --- money. Just money, money, money. (ah, yes, "Cabaret.") Haven't seen a word about pleasure, knowledge, learning, exchanging info., etc.

There's a big difference between "faith" and "fact." My opinion is the faith-based TPG "certification" is not based on facts.

As is often the case VKurtB's ignorance and arrogance are at the forefront. I have examined all of the tags, seals, bag, and done the research that NGC clearly did not do. (The "escape clause" for a TPG as it is for VKurt'BS' is "opinion.")
My comment: "The materials available do not support the descriptions. Ask the TPG to show you copies of all the tags, seals, etc. Then, go do some original research."
 

The practical ideal of mutual support of central banks was more promise than realization. One of the largest world economies had no central bank, and once one was established in 1913 it was not until the 1930s that it actually acted as more than a fancy Clearing House and money distributor.
I feel that the real poltergeist was a combination of technological innovation and vastly uneven expansion into consumer products. This kind of economic growth could not be constrained by a simplistic approach of locking in a single standard. The reality of mass produced, durable goods - formerly a very tiny part of developed world economies - became the results of complex interconnected business processes. Upward wage and price pressure prior to WW-I were exacerbated by the war's demands, and the immense shift of gold to the US (a depreciation of gold value comparable to the California discoveries).

Here's a little historical perspective - from the ANA August 1920 convention.

100% counterfeit.
