  1. Morocco, Benduqi, AH 1277. 5 known examples (original mintage unknown)
  2. I hope for your sake that it is genuine... but I have strong doubts. That looks fake.
  3. While there is obviously a bit missing from that article, that is one of the most complete summaries available online. I'm sure Roger can fill in details.
  4. Oh, absolutely. I think you used the figure 25-100 strikes.... I'm not sure that's ever been proven, but I'm quite sure that the strikes from a newly polished die which produced PL finishes was quite small. I can provide statistics for how many PLs are known in a series compared to grading events, for many, many series based solely on my purchasing history. For those interested: Roger's research and experience mostly applies to the mint era of mid-1800's to mid 1900's. If you're talking about PL coinage after 1960.... it's different.
  5. While that is true, planchet surface also does not preclude PL or mirrored strikes. I'd love to see a "clock" as the captain mentions, but I have a couple of off-center coins myself which show this effect. Rough planchet, PL fields.
  6. I'll just add, if you saw it dated 2014 then that means it was top that year - but was then dethroned in subsequent years. It's part of the game, if someone takes it away from you then you have to go buy nicer coins and win the top spot back!
  7. Does anyone have a link to this article? Sounds interesting, but I'm not a subscriber.
  8. I got one too. I thought that was a really nice sentiment. Thanks, @dena
  9. I checked - they have a category for the company, but it is empty - no catalogues available.
  10. Hardcovers are usually special issue, limited release. They often trade at a large premium, as they are higher quality.
  11. Yes, I'll agree that this seems to be the case. There are a few very passionate die marriage collectors (the Bust Half Nut Club), but my understanding is that membership is lower than it used to be. And I'll also agree - pursuit of the grade, avoiding problem coins, and looking for registry points may be a strong contributing factor.
  12. Obviously, this is super rare. CoinFacts shows a problem free PCGS VF-35 sold in 2011 for $94k. The one DWLange mentioned is currently up on Heritage, VF details with a hole: Based on the sale of that one, I'd expect the newest example to be worth a bit more than the holed example - holes are murder on value! Even though this is F details vs VF, I'd rank the newest example higher. The advantage of the holed example is the Reiver pedigree, which is fantastic.
  13. I only keep auction catalogues if they can serve as a reference. Something like a Heritage FUN sale has a lot of coins, and it may have one or two detailed descriptions, but its not worth filling up space on my bookshelf. However, for really specialized collections, sometimes the auction catalogue can become the standard reference. For example, I recently purchased "The John W Adams Collection of Comitia Americana and related medals," put out by Stacks and written by John Kraljevich. Absolutely spectacular, detailed, and comprehensive work (even if it is only 150 pages or so).
  14. Congrats to everyone who won a Registry Award! I recognize at least a few names on this list. You all should be super proud!
  15. I have hit refresh approximately once per minute waiting for the results. You're killing me!
  16. Starting in 2009, the date and mintmark were moved to the edge. Most people don't have any idea what these dollars look like; I'm almost certain I've never seen 3/4 of them before today. You can see them all here:
  17. Good luck on your set! A collection of 1795 coins is a very advanced undertaking, and I wish you luck! To answer your questions: 1. First, the die clashing does not automatically make this O-116, but a clash in this area is seen on the O-116. Clashes can appear on numerous marriages, and a reverse could be paired with a difference obverse (and thus be a different marriage). The identifiers for the O-116 can be found here: 2. There are two primary references for early half dollar die marriages. The first is Overton's "Early Half Dollar Die
  18. This has been treated with a substance called "MS-70." It is highly controversial, and a quick search of this site or of google should show you why. However, coins with this look are very often slabbed, so it is no surprise.
  19. I recently watched a video about this. Not sure if this is the same website as the OP in this thread is referring to. It is quite basic so far, but shows some interesting ideas.
  20. The problem with resurrecting really old threads like this is that many of the pictures are gone.
  21. It wasn't until 1893, with AG Heaton's "Treatise on the Coinage of the US Branch Mints" that people really began looking at or for mintmarks. His book is obviously quite outdated and has many inaccuracies, but it really did influence collectors at the time. You can read it on the Newman Numismatic Portal, here:
  22. Mark, a rusted die exhibits as a pimply surface, and does not give streaks like shown. I see no evidence of a rusted die here. I honestly think what I'm seeing on this coin is a planchet issue
