Hoghead515 is piling up the correct answers ! Great work!

Yes, very lightly struck --- so much that it's invisible....

Coinbuf answered your question just fine. Circulation abrasion is also smoother in appearance because it is of lower pressure than deliberate cleaning and is random.

The scratches and other marks are present, your photos merely make them more easily visible. An experienced collector will easily spot them without help. As for color, the combination of texture and color is not natural; however, your photos do not seem to show typical chloride or sulfide commonly seen on acid "dipped" coins.

Nice !

Nice EF condition but, like the 1903 quarter, scrubbed into limited desirability.

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.
