EF condition but scrubbed and unnatural looking.

Certainly. They also list the same die pairs under multiple numbers. "VAMs" are not strictly die pairings but varieties based on idiosyncratic criteria.

More likely cleaned with baking soda and a toothbrush, or possibly just soap and water.

They might have been in paper rolls, but not likely they were from the 19th century. (I was referring specifically to your 1883-CC dollar. Others have been in circulation a little or polished - like your 1904-O.

Member FlyingAl has opened a thread on the PCGS message board where he begins a discussion of really useful research into the so-called "1964 SMS" coins. It's certainly worth a detour to read. https://forums.collectors.com/discussion/1094235/origins-of-the-1964-sms-coins

The only "LAM" error I can see is the one where a buyer accepted the 2x2 scribbles as truthful. In that case it was a "Lam to the slaughter." 18th century US banks rarely wrapped coins. They were usually received in bags then broken into smaller quantities for use by paying tellers. Small paper envelopes were commonly used. [PS: The coin is MS-60 or 61, probably pulled from a GSA sale holder or plio envelope. The photos show no evidence of "proof-like" surfaces.]

Be sure the scale you buy has enough upper end weight capacity for the bulk amounts you anticipate --- you don't want to be weighing 500 dimes one-at-a-time. One other small item. Bulk silver that people bring to sell is usually dirty. Allow for this when you buy or sell.

For weighing bulk silver coins, you won't need low weight accuracy. Accuracy to the 100th gram is over-kill. You will likely be weighing small sandwich bags of coins, so you need higher capacity -- say up to a kilogram. (32.1508 T oz per kilogram) Be sure to weigh the container separately and subtract that from the gross weight. For this purpose a $25 digital scale will be fine. Almost all are made in China and they are so inexpensive to produce that the quality and reliability are almost the same -- until you get to really good scientific grade instruments.

The date/mint are common in uncirculated condition due to the GSA sales. Your coin is one of those with a lot of scraps and marks from being jostled around in original bags (1,000 coins in a bag). The scrapes and deep gouge on Liberty's face limit it to MS-60 or 61, in my opinion. As for what to expect to receive in selling it -- possibly $150. Demand for this kind of low-end Carson dollar is limited. As Sandon noted, he obtained a nicer coin for a little over $200 at auction.

Do you want cheap or accurate? A scale is only good for weighing raw coins or medals.

What they tried was not what I outlined. No TPG has ever made a meaningful attempt to automate. A working system, sensibly engineered by educated professionals, would cut staffing while vastly improving quality and consistency. It would also end "gradeflation" unless deliberately altered. Look for ways to succeed, not models of failure.

FYI - the precise alloy is an excellent means for identifying highest quality counterfeits. The crooks match physical and visual appearance, but alloy is much tougher.

What are the rarest Chinese coins in nonexistence? How many are slabbed?

Mechanical doubling. No special value. Also, it appears the "S" fell off the obverse.

Then it "wouldn't be." The system must not "bend" bin assignment. Normal system testing should reveal any programing errors. Look-up tables will also increase image processing speed, freeing clock cycles to handle transforms necessary to fully evaluate the coin or other object.

Hoghead515 can pick up his prize whenever convenient. ... Oh, realized no prize was mentioned....OK , well how about a hearty handshake and a sincere "Well Done."

Thanks. Hmmmm....sounds like a term referring to bias of some sort. A catchword or emotional trigger. Don't understand its meaning in the OPs first comments, but not of any real importance.

Any computer system (AI or any other popular term) has to be given parameters for the work. "Grades" would all be within those limits and errors would probably be far lower than human capabilities. This requires empirical-based internal standards for each design type. Luster, and related opinions are not relevant....those are market decisions at time of sale. An automated system is ideal for modern cookie-cutter stuff, and is actually an extension of automated Q/A used by all the world's major mints. The time to scan, analyze, and report a dollar size coin is measured in milliseconds (or fractions thereof), and one must presume this is done simultaneously for both sides. Also, is there any reason to remove a modern coin from its capsule? Leave it as it came from the Mint. (But must avoid polarized light sources.) This will eliminate handling and possible contamination. Then, use the same capsule inside the certification holder. Saves a lot of time, money, handling and potential damage.

This is touching on "Gnomen Clattle" outstanding in their field.

1 second, 24/7 M-Sun, and holidays for 3 coins at each second. The SW is much faster; only physical movement slows things. Good workflow automation would eliminate most handling so there are multiple feeding arms and multiple retrieval arms. One conveyor can handle several of the same coin simultaneously (most efficient) or several of different diameters (less efficient). US Mint already has most of this automated as described - and it's largely done inside a clean box. Capsules are filled by automation. Min 216,000 per 20 hr work day; but using the multiple arm fill & remove you could triple that. Plus, the machines record all the data and can calculate Q/A statistics, and predict SW or HW failures, etc.

Well, we have an early winner! Manganese is correct. "Manganese is used as a whitener and preventive of oxidation and it also tends to make the ingots less hard, and if carbon is present, to rid the melt of this deleterious element which, if present in sufficient quantity and annealing temperature is unduly high, will result in brittleness. The addition of manganese may be as high as 0.0075 percent without bad effects....With regard to manganese, this metal is added to each melt of ingots in the proportion of 1/20 of 1% of the weight of the melt." "Methods of Coining Five Cent Copper-Nickel Coins in United States Mints at Philadelphia and San Francisco," December 19, 1938. [ RG104 Entry 328H Box 2.]

Holders have no standard or controlled weight., so there's no meaningful answer to your question.

...Cheese Doodles ?

The software has existed for 30+ years, same for optical scanners and compactors. Database would have to be prepared along with the numismatic rules and controls, but large parts of that exist from current workflows and tracking SW. (it's kind of like inkjet printer ink -- where the companies try to scare and scam consumers into buying over priced "Mfg Brands."

Thank you. I recall someone on TV trying to explain it - they failed. What does this have to do with coins? Are there coins with people sleeping on them -- like the Rip van Winkle commemorative - and this was when Rip woke up from his long snooze?
