Really wish NGC would fix the Krause data in their World Coin Priceguide

    I'm not referring to updates. I'm referring to glaring errors.

    I have seen this ridiculous glitch again and again. Here. Look at this listing. Notice anything wrong? Compare the prices in the VF and XF columns. I stumble across this weird error all the time.

    Now, I know how enormous the database must be, and there is only a tiny handful of people available to work on it (if that), and it isn't a high priority for them (obviously).

    But absurdities like this do not help their credibility much, particularly when the catalog is rife with them.

    My main suggestion is that they should add a "report errors on this page" link, is all, so things like this could be flagged and reviewed.

    But they would then get an avalanche of reports, I suppose.

    *Irony alert: I edited this post to correct a rather heinous typo of my own, which I had overlooked the first several times I read this. :rolleyes:

    physics-fan3.14 You got any more of them.... prooflikes?

    I'm sure they have an automated bot that imports everything from Krause, and they don't actually look at it.

    The only time they look at it is if someone reports a new sale (which I imagine is rare), or if someone complains. If you send them a message (email, or on the NGC forums), they are usually pretty quick to correct issues.

    Now that the parent company of Krause went bankrupt, I'm really curious to find out what the future of that resource is!

    My point is that nobody is going to go through the trouble to do that every time one of these glitches is spotted, though if there were a "report errors" link on each page (even one that did not require text input, but just a "please have a human review this page" flag), they might get reported more often.

    I share your interest in the seeing what the future of the Krause resource holds. I hope it is a promising one.

    For the type of error about which you are concerned, a program could easily be written. Algorithm would be: if price of coin in particular grade is greater than price of grade immediately above, then flag. The program to do and report the flagging would be relatively simple and could go through the whole database quickly. Responding to the flags would be a lot more work. Apparently neither Krause or NGC has considered the problem big enough to invest resources to deal with it.

    For some US coins, a lower grade coin can be worth more than a higher grade coin because of lowball collectors. A PO1 coin can actually be worth more than a F15.

    An AU-58 coin is often worth more than an MS-60 or 61 as well.

    Yes. Such an algorithm would be helpful, at least to weed out stuff like this. I've seen some 18th century gold coins with a high value in the VG column and then it skips to XF, which is worth less than VG. Laughable. But annoying.

    The world coin info on NGC's website is beyond comical, it is ridiculous. I don't even like to visit it.

    It seems to me like the values that are given are hard-coded somewhere, something like $2 for base, $20 for silver, and $1350 for gold iirc. Figure out where those come from and change them to null, and it'd fix the display issue.

    But yeah, NGC is pretty much useless for world coins imo. Numista is way more useful for catalog purposes, and there are a lot better places to figure out a value.

    Like...?

    Be it ever so quirky (and NGC's version even moreso), I can't think of any other one-stop location with such wide priceguide coverage as Krause. (Yeah, I know- eBay closed auctions- but that's hit-or-miss.)

    Numista's growth is encouraging. If I could count on it for valuations, I'd use it more than NGC/Krause.

    I use auction prices realized for world coin prices and find it to be more realistic than any of the price guides. Both NGC and PCGS have these for world coins. NGC's is easiest to find; just click on Resources and then Auction Results.

    If you go to Auction Prices Realized on the PCGS website, you'll find only US coins. However, PCGS does maintain an excellent database of auction prices for world coins. There are a few tricks for accessing it. Easiest way is if you know the cert. no. of an example coin. Just go to cert. verification, type in the cert. no., and at the bottom of the page that appears will be a link to auction prices. What if you don't know a cert. no.? Well sometimes there will be pictures of slabs in the registry, and the cert. no. of an example can be obtained from that. Heritage Auctions usually has pictures of slabs in their archives as well.

    You can get a partial listing of auction prices via the PCGS registry too. If there is an entry of a particular coin in a set, the coin date will be a live link. Click on it, and a page with auction prices will appear. The information provided will not be as complete as that obtained via cert. verification and will not be in as convenient a format for downloading.

    I like to use both PCGS and NGC world guide but I find Numista much better. For auction prices, I use ebay, heritage, and stacks bower.

    I don't recall seeing the NGC contract in the list that were assigned with the book sale... But I also didn't look that deeply it was like five hundred pages...

    At least numista is crowdsourced... When I went to add my Titaniam moon landing piece and couldn't find it, I could add it... Unlike them krauss wasn't updating the catalog with the 2014 Kennedy half's andaI hadhto.email a dozen people.
