This is not meant to be an "everything not listed on Numista topic."
Just things make you say, Hmm.

How is this coin "reported not conformed"

The original auction listing (through your acsearch.info link) says "According the Standard Catalog of World Coins this date is reported, but unconfirmed. This would suggest a rather limited quantity and poor survival rate and as such should be considered quite SCARCE."

Edit to add: Perhaps the note was made before this coin was certified, so there were records of the coin being produced but there were no known surviving examples at the time.

Thx for starting this thread @keith. I'm looking forward to seeing how we might improve numista's listings with this thread.

I have been adding coins I find to Numista when I see that there is not one yet listed, I also submit/suggest corrections if I notice errors in a listing.

In this case because Stack's and PCGS both attributed the coin wrong.

Your coin is this one, Schulten 2681. https://www.acsearch.info/search.html?id=623806

It does not appear to be in Numista yet ... so we know what happens next

Yep. Numista is crowd sourced, so report anything new, corrections, etc.

A couple of years ago, The Royal Mint (UK) started selling a Titanium version of one of their commemoratives at the ANA WFoM. It was neat, I bought one and then looked it up on Numista to find it wasn't listed. I reported it, including photos I took on the show floor. By the time I returned to my hotel that evening, the listing was up.

I took the opportunity to report a new variant for the Israeli 1 sheqel (...OK, "shekel") coin when I got one in change. At the time Numista had some of the other denominations for the 2022 update but not yet that one.

That entry still had my photos

Keith67's last two coins posted in HFBCYG hit a weak spot in Numista: coins that are relatively rare, but not extremely valuable.

Because it is crowd sourced, the coins that have been in Numista the longest are the common ones (both new and old). The extremely rare, splashy ones from the more "collectible" countries are also there.

But because of the crowd-sourced model, coins which relatively few collectors have (there are only a handful of examples of Keith's coins across 15 years in acsearch), but are not famous or sought after are sometimes missing.

Getting back to the coin that started the thread ... If blame needs to be assigned, it's probably with Krause. They called it wrong in this listing: https://www.ngccoin.com/price-guide...-duid-382578
Probably PCGS followed, and then Stack's.

It's good to see the discussion about Numista, which is not perfect, but sometimes other places have messed up even worse

Good to bring this topic to cross coin worlds both here and Numista where I love contributing over there also!

I too have a few more items I need to add to Numista in the coming days to continue to add to the world catalog and to help out wherever I can...

I have even been known to edit already established N#s for obvious errors or could help by adding new information on new varieties of similar coins. I have also pointed out inconsistent data, such as a few days ago, I was perusing the enormous tokens and medals larger than 200mm and found several strange data points like the item was over 600mm but 700mm thick meaning it would have to be a very hollow huge cylinder which doesn't make sense...

I've found several errors on NUMISTA, most regarding Spanish colonial cobs ... my efforts to correct them have been for naught, as the fellow in charge of that area seems to want to stick with his "opinion", rather than what is provably correct ...

...Very difficult to institute correct changes when battling someone's ego ...

Yesterday I caught a mistake in the other direction ... a coin listed as 1.9 mm diameter.
All those modification requests help make it a better catalog.

The mistake in Krause with Keith's coin is especially problematic. Ultimately Numista is "derivative" in the sense that info on many coins gets copied from other places like Krause. So mistakes in Krause have a tendency to get propagated into Numista until someone notices and corrects them.
That's unlike the "common sense" mistakes commented on by mrwhatisit.

Well you don't have to worry about NEW errors in Krause, it's dead.

I would say "living dead" (since it's Halloween season). As we see from the lead post, its old errors haunt numismatic accuracy from beyond the grave .

The hexagonal Egyptian 2 piastre, commonish and always popular with collectors of unusually shaped coins, is listed in many catalogs with a mintage of 32 thousand. The type is far too common for that, and this gets sporadically noticed.

Apparently the true mintage is 32 million - but it's hard to get sources, as Krause had been getting it wrong since the 80s, and few other sources list that type at all...
