  1. A bonus halfcrown for me too this week. Bought for stock, but with much of the crap removed it shows the obverse mark to be crescent over book, so it becomes one for me. Crescent is a rare mark for James I and only used on gold. Book is only marginally less rare. Up to this point I hadn't positively identified this overmark on any coin to add it as a requirement for the initial mark section of the collection.
  2. Wrong description - not plume over shield and Adams was 2005, not 2008. The obverse initial mark warranted a footnote in the Adams sale. TWW, who catalogued it, thought it might be tun over a vertical tun, but not tun over crown for either side. Bull catalogued it as Tun over Crown both sides. The complete absence of the cross normally seen on top of the crown does give rise to some reservations about this overmark.
  3. If you want to get something done - ask a busy man.
  4. Three important variables here - the temperature of the ice and surroundings and the amount of salt used. Adding salt to ice or water will depress the melting point with a higher salt concentration depressing the melting point further, so adding a little salt to the top of an ice cube will cause it to melt at the surface. The concentration will depend on the amount of salt added together with the amount of liquid water produced. To get this water to refreeze will depend on whether you can get a greater heat transfer from the solution into the ice cube than from the surrounding air into the salt solution, sufficient to reduce the temperature of the solution below the freezing point. Therefore, ice at a lower temperature than the freezing point of the salt solution will cause the latter to freeze around the string as long as the thermal conductivity is greater from the liquid to the ice compared to the surroundings (water or air) to the salt solution. The colder the ice, water and air, the better. Thermal conductivity is better from liquid to solid than gas to solid, so doing the experiment in air should be easier, reducing draughts will assist this.
  5. There's no shortage of ebay sellers cleaning their coins prior to infection
  6. Special Delivery and Signed For items are now being pushed through the door to avoid close contact (signing their machine). I'm not sure how this will affect various parties' liability. I guess the message is, if you are happy the postman will deliver, OK, but if you are worried about them going missing, ask the seller to delay posting. I had my Lockdales lots arrive today, no problem.
  7. My post office is open as is Hermes drop-off, so shipping is still an option. Royal Mail delivers, or at least did so this morning and Hermes dropped something off yesterday. i.e. it is possible to function. I'm spending the time not going to fairs by listing some of the many things on the website that I haven't got around to doing so far, putting some things on eBay and sorting out the numerous storage boxes of coins in the pending pile. I think most dealers have a lot of things not listed on their sites, so stock is not necessarily going to be a problem. Prices must take a hit somewhere assuming some people will have lost their disposable income, but at the top end, money is not a problem with only a bunker mentality inhibiting spending. The world unlikely to run out of people on ebay buying things for a quid, so this offers probably the strongest market for selling into. Stock markets coming off 20% will have made a few people switch into alternatives. Unusually, gold has not spiked to any degree, so either people are sitting on loads of cash, or they are buying alternative assets. Property isn't an option as viewing/surveying etc is problematic, so it boils down to assets you can buy over the internet. Good for coins, or at least relative to some of the alternatives.
  8. I was doing something similar by trying to add two segments with similar chord length but differing radii. It all went t*ts up when it dawned that I had a second variable (the angle) in the equations - at which point I realised I had forgotten about integrals.
  9. Given the number of ships noted and the ability to count the number of dies used per ship type, it should be possible to work out a fairly close estimate of the number of dies employed in total and the number of coins made per die pair. At one ounce of copper per penny, that's 35840 penny equivalents per ton of copper and a shedload of dies. Let's test the dedication of some of you penny collectors to destruction.

    Ebay's Worst Offerings

    But on the other hand, they are going to lose over £30 in fees and shipping. A bigger negative is the absence of pictures of the other side of the coins. At that point the price becomes irrelevant.
  11. Further to the recent discussion regarding coin tickets and their attribution, the idea of having a stand-alone thread was mooted. Ideally this will be a list of attributed tickets alphabetically arranged by name with a different post for each person. It would also be useful if examples of handwriting attributed to distinguished past collectors could be added as this may assist in the future when confronted with an unknown ticket. There is a useful article in the 2001 BNJ entitled 'Coin Tickets in the British Hammered Series' by Robin Eaglen, but nothing directed towards milled coinage. A link to the BNJ article is http://www.britnumsoc.org/publications/Digital%20BNJ/pdfs/2001_BNJ_71_13.pdf It would help if the thread was a reference tool rather than a discussion board as this would keep the list clean and thus assist when searching. It would also help if admin were to contribute suggestions of what is and what is not possible when it comes to presenting the information in a workable form. I'm hoping (possibly unrealistically) that the ability of Admin to shunt files around can be extended to arranging the entries, or if not, at least an index at the head of the thread with the post number/name to aid searching. The ability to append information to an existing post would also be good.
  12. The first 6 is clear and unambiguous and consistently so across the date range, but the second is a thin winding line. I've seen this before, but never something that is unambiguously another 6. Anything with '6' as a last digit is invariably on a compromised coin. The Maundy 5s are considerably thinner than the farthing 5s despite being of similar height
  13. We were lucky in 1999 as we were in Germany and saw it from a point about 30 miles or a bit more west of Munich. Quite fortuitous as it was cloudy all morning, then it cleared up half an hour before totality. After the eclipse and within 10 minutes of getting back to Ammersee, it p'd it down for a couple of hours. Apparently, this was the clearest sky for viewing all the way across Europe until Romania. Quite chuffed as it had been a must do appointment in the diary for the previous 30 years.
  14. Nah, there's only one place in Wyoming worth mentioning - Armpit. See image from 1982. It's still there, but looking at recent pictures the walls of the sheds have been upgraded in the interim. When I was there, a guy lived in one of the huts over the summer, then went down into the valley during the winter to work on the oil wells at Lovell. As guests, we dossed in the other shed where he kept his dynamite and ammunition! The mining bucket in the right distance was inscribed 'Welcome to Armpit WY. The threshold of a new reality'. The place was one of three uranium mines from the 1930s, the other two being Groin and Earwax, both sadly no more.
  15. https://m.youtube.com/watch?v=1ymR82yFYnk&feature=share You couldn't script this.
  16. All is not lost - the tabloids are still printing.
  17. An error is simply that. There's nothing to say an overstrike should be logical, nor illogical. It could be absolutely anything.
  18. Hopefully the producer and scriptwriter
  19. Is anybody fluent in squiggles? Attribution of state and date would be appreciated. Weights as follows starting top left and clockwise 8.41g, 3.39g, 3.44g. 2.72g and the one in the middle is 0.41g. Thanks.

    And the other sides.
  21. My eldest daughter was asked by her teacher, 'If the plural of hippopotamus is hippopotami. What is the plural of whataclotamus?' To which she immediately replied 'It's a whataclotareyou'. Result - 15 minutes extra work. Most unfair given the mental flexibility shown.
  22. Glad I'm not the only one. Try looking half a dozen posts up the page
