  1. 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.
  2. 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.]
  3. Holders have no standard or controlled weight., so there's no meaningful answer to your question.
  4. 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."
  5. 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?
  6. Held over a fire or in an oven. Nothing unusual except for the scammers trying to sell these as "valuable errors."
  7. This is something most would not expect to find in their normal packet change nickels. We'll give it a couple of days before posting the material and reason for its use.
  8. If located, you will receive an FDC piece. Since the definition of "MS-70" was omitted, you might also receive a coin the a hole in it.... Talk to Quintus about this -- he's dealt with it before.
  9. "Artificial Intelligence" (AI) is no better than the data to which the system has access and the validity of rules of operation. Quality assurance systems in manufacturing has long been far more accurate, consistent and reliable than human "grading" in most situations. However, TPGs have never made the development investment to adapt existing technology to what they claim to do -- assess the "condition" of coins. This is similar to their rejection of empirical research and scientific method in their "guesses" about unusual specimens. Frankly, institutionalized ignorance might increase the number of submissions as submitters try to out guess the TPG "experts."
  10. The US Mint is capable of making coins of equal and better quality than the "old timers" made a century or more ago. But --- it appears the only one who can make that happen is the director.
  11. There are consistent legal and moral obligations to disclose all material facts and conditions when selling somethig. Period.
  12. The item might be a printed sheet produced by NGC and individually signed by Mr. Uram. The signature on every item would be slightly different if individually signed, and I doubt NGC would misstate this. It's not clear to me how this might have any meaningful value, or how it could be displayed along with the (ugly) coins. [EagleRJO - I was aware of attempts to have these imitation dollar coins made, but declined to support them without clear requirements to equal the 1921 Peace dollar design in all respects; I felt the 1921 Morgan dollar was, and remains, unimportant.]
  13. That's what the FTC suit is about - failure to disclose fees, misleading and false information.
  14. Nondisclosure of material facts, however, is fraud.
  15. Diagnoses: Ordinary circulation damage and discoloration. No numismatic value at all. Cure: Spend them. Preventive Therapy: Stop watching Goo-Tube coin videos.
  16. Yep. Good judgement. How would the OP describe and illustrate this slabbed coin?
  17. Must get hot in those long black robes.... Are the gavels used to knock holes in glass cases to get a better view of the coins?
  18. Look on the internet for auction sales at CNG and others. Not clear if your coins are real of fake.
  19. Nope. The alloy was brought up to US Mint standard by adding pure copper, and the resulting ingots were chemically identical to 95-5 used in 1942 -- a trace of tin added to meet legal requirements. [See the book United States Experimental and Pattern Pieces of World War II for facts.]
  20. The small images suggest the assigned grade is correct. Tarnish, unless it's really bad, has little effect on ancient coin grades. I don't know what is included in the additional service -- maybe they'll tell you which mint was used. "Lifetime attribution" has no meaning to me -- how does NGC explain it? (The coin in my post is graded FDC.)
  21. Noting is misrepresented -- unless referring to the connection between an ugly dog and a trained working dog reactions. Did Quintus Arius write this one for you?
  22. According the the article the people named were paid by the "gold IRA" frauds for their endorsement, and that was aimed specifically at a vulnerable population. I have no involvement in any aspect except to point out the abuse as it relates to gold coins and medals. Analogous situations exist for other products such as "brain supplement pills" that are chemically impossible, but targeted to the fears of old people (per FTC suit).
  23. I see no "rainbow" toning in the photos, merely common tarnish. With a grade of VF the implication is that the coin was dipped and allowed to tarnish naturally. Only an FDC coin would have original color.
