  1. I don't see the so-called "Blakesley Effect," so I doubt it's a clipped planchet. For more on the Blakesley Effect, Google or see https://www.coinworld.com/news/us-coins/2015/06/how-to-identify-a-genuine-clip-coin--collectors--clearinghouse.all.html This link has a decent article but it was difficult to make the thing load. I finally has to use IE because it wouldn't load in Chrome or Firefox. Mark
  2. ATS I saw a link to a lawsuit in which NGC played a key role: https://caselaw.findlaw.com/us-2nd-circuit/1709047.html In that file, in “Part B The Defense Case” the defense “expert” checked NGC’s grading of 1,671 coins. These coins went through what is apparently NGC’s usual 3-person grading in which two graders initially grade the coin and then a finalizer determines the ultimate grade. Of these coins, the initial two graders had the same grade 90% (!!) of the time. They differed on only 167 coins and of these coins ONLY 11 had a discrepancy of 2 or more points. It’s hard to tell the range of the grades, but apparently they ranged from about MS65 to AU50. I presume that a difference in grades of AU55 and AU53 would count as a difference of “2 or more points,” even though it’s actually a difference of only one grade. Nonetheless, I think that the consistency of NGC’s graders is truly remarkable. Mark

    How to deal with MAC and CAC

    I also haven't seen any changes. But given Conder101's expertise in slab history, I hope he has been following CAC stickers a LOT more closely than me.

    How to deal with MAC and CAC

    Hey Conder101: Given that you will always be my expert on the history of PCGS slabs, have there been any changes in the CAC stickers over time? Thanks! Mark
  5. What a great time you had and that I got to enjoy! I can't ever attend the Summer Seminar due to my job but after your post, I feel like I've just attended my first! Thanks so much. Mark
  6. I vaguely recall that if you go ATS roadrunner knows some of Mr. Tulving's history. But I hasten to add that I may be incorrect. Mark
  7. Mark: Other than cleaning, what is the most common way for proofs to acquire hairlines? For 19th century proofs, was it perhaps their storage by collectors? Thanks in advance! Mark
  8. messydesk: !!! More seriously, I'm surprised that NGC did not make the Chinese boxes red given that red apparently means good luck in China. Mark
  9. Can't see much of the details of the coins but the quantity shown in the picture is still very impressive. I bet it was just a lot of fun to lay the coins out in order to take a picture!! Your picture definitely gives me the incentive to visit my SDB and do something similar. My picture won't be as impressive but the fun will still be there! Mark
  10. I am DARN glad that Carr's "coins" can't be CACed. Think about how long that thread would be! Mark

    Please help a newbie!

    I second Raisethis2's suggestion to contact Mark Feld BEFORE you even think about venturing into a local dealer. Mark is a highly qualified, highly respected dealer working with one of the largest coin companies (Heritage) in existence. His advice will be sound. Mark PS: I have no connection with Heritage other than buying coins from them in their auctions.t
  12. I'd rather mangement poof the post than the poster because it would be a royal pain in the rear to track down some of you that I really like to follow! Mark
  13. coinman_23885: We could test my "theory" that trolls and hard feelings lead to people leaving by getting into a real nasty disagreement in this thread to see if we drive anyone off. More seriously, I certainly agree with you that fewer threads leads to less interest. The problem, of course, is that in turn less interest leads to fewer threads. I like SkyMan's suggestion for people to post photographs of their NEWPS to unique threads. Unfortunately I have zero skill in taking photographs so unless the coin comes with pictures, I won't be posting much. But I sure enjoy looking at other collectors' purchases. Mark
  14. Idhair: To tackle your op, I think that some people have left due to the presence of a few trolls who post an innumerable number of nonsensical words in many posts on many threads. In addition, there is one particular topic that virtually always leads to hundreds of posts that shed no additional light on a well worn topic. I know that I grow tired of these posters and threads and when one is roaring, I don't glance over here for a few days to let it settle down. Given the very lightly moderated nature of these boards, I don't know what can be done about what I see as these two problems. It seems to me that these boards get more new collectors asking basic questions about their coins than do the boards ATS. But these new collectors 1) hardly seem to stick around, and 2) aren't going to provide much motivation for more experienced collectors to continue their posting. Mark
  15. As I said before, this is a thoroughly fun thread. I anticipate seeing something beautiful when it's done! And congratulations on the NCIS job. You have to let us (or, actually all I care about is me ) know when your episode airs. Mark
