  1. I assume Ebor is York other than that I can offer nothing on its provenance accept it seems an extremely well struck coin for a hammered sample.
  2. Given the large amount of .925 silver pre 1920 George V coins that are still around which are in around VF condition suggests that a significant number were hoarded at an earlier time. Obtaining the 1920s issues in the higher grades is far more difficult.

    PCGS

    Hi Vicky I've long since upgraded this coin. As it happens with a PCGS MS 63 version which I obtained from Sterling & Curency of Fremantle, West Australia , for a good price. As it happens I brought the coin not the grade. That's the good thing with slabbed coins when the stated grade and the true grade coincide. Which is not always the case as demonstrated by the subject of this thread..

    PCGS

    If you look at the PCGS photos included with the listing it is obvious the coin has been badly cleaned and IMO should have been noted by PCGS. If a coin like this was listed in the Coin of the Week thread of these forums any number of people would comment on the regular scratch marks like the coin shown below.
  5. Don't mess with the wilh of the people. The people have spoken, get used to it. Weekend Australian.

    Did the CGS numbers reconfigure?

    IMO CGS along with other TPGs would be better employed in maintaining consistency in their grading practices.
  7. PS according to CGS it's a Freeman 13 which I think is one of the more common types. As far as I am concerned it is a good example as I do not collect minor penny types. As far as I would go would be Low Tide , KN & H mint marks.
  8. My latest penny received to day from the Coin King CGS 75
  9. Nice coin. I f you had issues i including both the obverse and reverse of the coin on one post you could use an image processing app to crop the images, combine into one image and then resize into a file size of .49 MB that the Predecimal For,um supports. One called Infan View will do this for you. It can be downloaded for free.
  10. Perhaps the days of "good" speakers is over. The approach now is to use fairly ordinary speakers and enclosures and compensate for their defects using digital equalization where the venue is scanned by a microphone its response logged and the equalization calculated to compensate for the defects of the speakers and the venue. I first saw this demonstrated when I was at Uni where one of the student projects did just that using a basic PC, and an isotropic microphone plus an 8 bit ADC and DAC to digitize the test frequencies and the response of the system to them. I can remember thinking what a good idea it was. Of course the speakers would have to be able to handle the power and not saturate which would generate large amounts of harmonic distortion. The enclosure has always been an important part of improving speaker performance. For example the base reflex enclosure which was effectively a mechanical equalization system to improve the base response of loud speaker systems. Speakers have always been the weakest link in the chain because of the non linear nature of magnetic circuits due to the effects of hysteresis and saturation. Hence the Quad electrostatic speaker which employed an electrostatic transducer to convert the electrical signal into audible sound which is linear and does not saturate..
  11. A rare date. I think it would be difficult to find a better coin. It all depends on price. London Coins have a CGS 78 for GBP 680. Their prices are inflated and your coin IMO is better than the London Coins offering but it gives some idea. I've seen other 1925 florins of lower grading GVF to aEF for around GBP 250. I hope this helps
  12. Thanks. That's good I hope you have success this time. Just to make you jealous the road outside my place is littered with poinciana seeds. Well and truly on the mend. It wasn't the big C.
  13. Q What do you call someone who has had a colectomy. A Gutless. PS I had one 2 weeks ago and recovering well.
  14. Very nice. I found welding glasses very effective for photographing an eclipse. Perhaps not recommended but effective.
  15. I like the Colonial bit probably Australia or S A colonies.
  16. I was watching the news today concerning a hoard of medieval coins recently discovered by metal detectors in SW England. The commentary went on to say that they had been cleaned by conservators of the British Museum. Which raises an interesting question. When should a coin be cleaned and when shouldn't be cleaned? The coins when they were discovered were filthy (not unexpected as they had been buried for the best part of a thousand years) nevertheless they were cleaned by expert conservators and this action must impact on the coins in some way. Given the cleaning of these rare coins has taken place and seems to be standard practice for ancient coins why does cleaning of more modern coins attract such negative comment on theseforums given any cleaning performed is performed with minimum impact of the coin ie only dirt and ugly tarnish is removed from the coin's surface as what has occurred with this hoard. Insteadany suspicion of cleaning seems to brand a coin for life often on the flimsiest of evidence as the coin cannot be examined properly from a photo or scan. As I have said before any high grade coin George V coin that has been put aside for close to hundred years or more and probably tarnished (toned ) during this period. Sometimes it becomes so bad that it detracts from the coin and cleaningwill enhance the coin's appearance and hopefully it's value. Of course the decision to clean or not to clean is a decision not to be taken lightly and my advice would still be if in doubt then don't. I still maintain that any bright hundred year old coin has probably been cleaned at some time in that period.

    Pictures

    An orchid in my court yard. It was one brought from Costco which I attached to a small tree when it had finished flowering. If you keep them in pots they tend to die from over watering.

    Pictures

    Did you use a telescope or a telephoto lens on your camera? In the past I have attached a digital camera to my X - Y 4" tracking telescope. and taken multiple photos of the object in question. As the X-Y tracking causes blurring of the picture there are SW packages (their name escapes me) that aligns the multiple images and building them up into a composite picture. They also contain all of the normal image processing, brightness, contrast, noise reduction, sharpening etc. A very nice picture of the moon.

    MS62

    I think you are right. An interaction between the scanning pixel size and the computer display size aliasing perhaps.

    MS62

    That's a very strange effect around the the Scottish lion? Overall a very nice fully struck obverse.

    MS62

    Some very nice 1910 halfcrowns.

    MS62

    It seems that the quality of strike for 1910 halfcrowns could be variable. Here's my 1910 halfcrown.. Firstly the reverse is a better strike than the obverse and I would grade it as UNC. The obverse is a weaker strike but given the reverse you have to cut some slack as both sides of the coin should wear evenly. As a result I would give an overall grade of gEF for the coin. In summary a very nice coin. I think I would prefer this coin to the PCGS example.

    MS62

    I noticed there is a video attached to the Ebay listing for this item showing the coin being examined. The coin looks much better in this video than the photos supplied in the listing. In the video you can see the edge of the coin quite clearly and that looks pretty good. Perhaps it is just a lightly struck coin. Like some of the replies say it looks better in the hand as it is hard to get a good picture when photographing through a plastic capsule. The PCGS photos don't help the coin either.
  25. A really nice obverse but weakness in Britannia's head on the reverse. It seems that getting a well struck obverse and reverse is elusive. This is my example not perfect but probably representative of the RM's output at the time.
