  1. Reholdering Copper Coins

    The same way that tarnish is removed from a silver coin. A mild acid solution is used to remove the oxidized metal. As it is with silver coins, the newly exposed metal is more vulnerable to elements. Toning forms a shield that helps to protect the coin. This is one of the reasons why dipped copper coins are more prone to toning and sometimes turning ugly. The chances of that go way up if the piece has not been properly rinsed. It's hard to tell if they have been properly rinsed. That's what happened to those Proof Indian cents that turned to dust in the holder. No doubt they looked good immediately after the dipping was done. I have a red copper piece that unfortunately has a partial fingerprint on one side. Is this, or is there, a recommended way to remove this? Or is it better to just leave it.

    How is a red surface created from a red-brown surface?
  3. Upgrade from 66 to 67

    Good to hear of a case where MS60 gets some respect!
  4. Reholdering Copper Coins

    When I first got back into collecting, I was fascinated by red coins, especially large cents. However, after hearing horror stories of unstable coins turning in holders, I decided to stay away and admire them from afar.

    What are ASGs?
  6. Hopefully NGC is listening to this thread. I do think this slab will help high quality coins and exonumia in NGC slabs.
  7. This has to be the largest slab ever made!

    Imagine the competitive registry set!
  8. In addition to being being able to shoot without prongs, raw coin photography allows light to hit the coin directly which makes photograph better, especially at the super high resolutions used by TrueView. As for time, with great coins, the extra work is worthwhile.
  9. You're right! Photos also need to be taken out of the slab as mentioned above. I just assumed they were in my post but it seems to not be the case. From a photography perspective, I think two of the most important things NGC can do is: * Offer a TrueView like photography service, per the above. * Offer clear gaskets (which is now offered for exonumia on request). NGC currently slabs many of the best coins, including world coins and exonumia. Those should have top flight photography services. Some coins can already be had with TrueViews, but many exonumia are not yet slabbed by ATS (and may never be?). Providing such a service integrated into Cert Verification would be a great service.
  10. Good to know, but it seems like the service doesn't provide image files like TrueView. Photo Vision provides images embedded in a PDF which is... interesting. It would be nice to have individual images at different sizes like ATS does. Also, it seems like the service could use some more promotion: * Image searches return a lot of TrueViews but no Photo Vision photos other than the one posted. This is likely a consequence of not providing images, but PDFs. * Photo Vision should be added to Cert Verification Page. The posted example above doesn't show the Photo Vision image: NGC 3317587-003. ATS will show all images they have. The following would seem to help the service: * Provide image files (instead of or in addition to PDF) * Provide image hosting with various sizes including Max size like TrueView * Include on Cert Verification page * Support image search on search engines
  11. Has NGC ever considered a high quality, out-of-the-slab photography service similar to TrueView? It seems like it would be an easy value add to provide given the number of excellent coin photographers that are available and used by some coin dealers. It seems like this would be useful for collectors in the age of prong holders. It could also provide some marketing for NGC services by having the NGC logo on high quality photographs. For myself, NGC does a great job of slabbing a lot of exonumia not covered by others and it would be great to have a TrueView-like service for these.
  12. I was checking out NGC slab boxes recently and in addition to the silver ones, I now see red ones (with gold lettering). When did these start coming out and are they official NGC boxes? In addition to the red NGC boxes, I've also started to see blue CNGC boxes with photos of what looks to be NGC slabs in them. Does CNGC have anything to do with NGC?
  13. 1804 dollar coin, real or fake

    Looks like it could be a Thai counterfeit. Do a search for 1804 dollar and compare. Yours looks a bit like the counterfeit shown below, including the 1 in 1804 and bust line.
  14. Trophy Morgan, or, will beauty fade?

    Why? The old holder shows stability. Agree with the benefits of older holders. This one looks particularly nice as it is an old fatty holder. Why be suspect of older holders? I'm sure a "cross" to PCGS was already tried...I'm always suspect of anything in Legend Auctions that's in NGC holders. They are self-proclaimed PCGS/CAC dealers. I'm generally less / not suspect of monster toners in NGC holders. Prices of monster toners don't reflect any price guide, PCGS, NGC or otherwise. Also, this is in Legend's Auction, not offered via their website which are different things. I think the old fatty holder for this rocks.
