  1. Sooooo....ask someone with more experience than you before you submit the coin. Take you time. Go to a coin show once they open up and show the coin to several dealers. Most will be helpful.
  2. Is this index meaningful? Is it reliable? Test-Retest Reliability Internal Consistency Inter-rater Reliability 2. Is it valid? Face Validity Content Validity Criterion Validity Discriminant Validity 3. What published evidence supports the index?
  3. The population estimates are the product of a simulation model built on multiple variables including: pieces destroyed from multiple sources, statistical validation and adjustment of TPG populations, behavioral patterns (such as tracing extant specimens; appearance ratios) and adjustments recommended by several academic people who regularly deal with population estimates (and validation of estimate) from incomplete data sets. Available hard data was/is always the starting point, and the model then expanded and adjusted to accommodate the gaps. A clear example occurs in the 1930s dates where we have exact quantities distributed and melted. After the estimates were completed for all dates/mints, David Akers' work was reviewed to see if there was at least a little correlation from his business-derived estimates and my data-based modeling approach. I then attempted to explain notable differences and select the most plausible final estimates. Fortunately, I had access to much larger and more reliable data sets than Akers, but unfortunately lacked clear information about how he really arrived at his approximations. I did not consult Bowers at all - being largely derivative and more indirect than presumed for Akers. TPG data began as early as possible - mostly around 1990. This helped identify the effects of resubmissions, crossovers and grade instability. My grade "bins" in the book are designed to minimize instability in what is inherently an opinion-centric system.
  4. If you want to preserve the coins for personal sentiment, consider buying high quality coin capsules from Wizard Coin Supply or other coin supply sellers. These will protect the coins from damage, and as well from tarnish, as the TPG holders. "Coin-tain" or similar capsules will cost a few cents each compared to $25 to $35 for "grading" from a TPG. With no present need for authentication or grading, why waste the money?
  5. For purposes of this thread, it is "value." The usual answer is "classic commemoratives;" at least that's what I've seen in posts for the past 20-years.
  6. Just curious --- what is an "underrated" coin? Popularity? Cost? Availability? Design?
  7. The explanation ATS seems to be that it is a software bug (not a 17-year cicada) not related to content. Maybe if you try again it will post.
  8. The pandas seem to be happy where they are. Why not allow them some dignity and not rip them from their homes?
  9. Did you examine the coin closely to see if the lines are complete? If they are broken or interrupted, you can save your money.
  10. The cows will come home wagging their tails behind them.
  11. Most coins found in small estates, likely such as your Indian cents, are not worth the expense of professional independent authentication and grading. Common Indian cents are worth less than a dollar each, if not damaged. To justify authentication costs, a coin should be worth a minimum of $150 to $200 wholesale. "Registry Sets" are collections of coins that have been graded by a third party grader (TPG). The owners compete with each other for having the most complete sets containing the highest quality coins. Some people get carried away by the competition and pay outrageous prices for common pocket change that has been given a very slightly higher grade than another, similar coin. "Alpha grade" refers to a single grade point difference on a numeric scale of from 1 to 70, with 70 being "perfect."
  12. That's a good place for them; but, add a note about them being counterfeits and where/when you bought them.
  13. This is in the "Book of Fractions." it originally came after the "Book of Numbers," but was removed during the First Council of Nicaea [pronounced: Ne ky 'a] (325 CE). when none of the Bishops could separate "numerator" from "deuteronomy" and they agreed to call the whole thing off.
  14. At least Treasury sent a replacement check.
  15. Negative exceptions will receive much more attention than the great majority of trouble-free transactions. Further, some of the "complaints" turn out to have a "mailer error" component such as sloppy packaging, lack in internal address card, no return address on package, failure to declare full FMV.
  16. The pragmatic response is Yes. Happens very frequently. However..... A "grade" is only the state of preservation - an objectively definable and measurable criteria. The others are, except for details, subjective opinions which might be of more of less importance to individual viewers. There is no pretense of "objective grade" if any subjective factor is included.
  17. A cent struck in silver alloy would also be much heavier than standard 3.11 grams -- about 3.59 grams. PS: Please crop your photos tightly to eliminate extraneous background. It makes them easier to examine and therefore easier for members to help you.
  18. Diameter punched blank Thickness punched blank Diameter milled blank Thickness at rim of milled blank Diameter finished coin Thickness at rim of coin Standard Weight 19.15 or 18.87 1.22 18.82 1.52 19.05 1.47 or 1.57 3.11g
  19. Nice! I happen to prefer the rejected 1927 (?) designs, but they are tough to locate. There is a group I cataloged by Paul Manship. I think, in the Smithsonian.
  20. Most of the coins are simply metal. When commercial need exceeds available supply, it can be a good business decision to melt any reserve supplies to keep the business operating. An individual who had purchased a quantity of routine DE during the 1960s-70s, could easily convert these "cheap" coins into cash and not report the capital gain. (Ignoring the foolishness of losing a much greater profit just by buying a mutual fund at that time.) I did some consulting for a company that had built up a large stockpile of rare earth elements in anticipation of future technological uses. Gold is not different, except its not a useful.
  21. As Oldhoopster noted, these are very likely counterfeits....especially when all three are found together....in the wilds of Philippines. Photos might quickly dispel any doubt.
  22. Goldfinger 1969 seems to have hit a gold vein of information and interesting discussion with this thread. Very, very few threads ever reach his length of posts or depth of content.
