How Are Krause-Mishler Numbers Set?

What if it is every 2 years? :P
I've run into a related problem now, where I know that a certain date is dated wrong in NGCcoin and numista (I don't have access to updated KM records). See, in 2015, Pakistan released a coin commemorating 100 years of Islamia College Peshawar. Except it was commemorating the date of 1913-2013. In 2015. Confusing, especially since the coin wasn't dated otherwise.
Note the date: http://www.sbp.org.pk/press/2015/IC...3-Mar-15.pdf (that's the press release from the website of the State Bank of Pakistan, the body that decides what coins to release, and under which the Pakistan Mint comes).

However, online you find this:

https://en.numista.com/catalogue/pieces71950.html

It's really messing up my dating system! Does someone have access to the KM catalogue who can tell what the it says on this coin?

Coins with "false dates" are not uncommon, especially for certain countries. Ethiopia and Thailand were both notorious for issuing coins with "fixed dates", perhaps even struck decades after the date that appears on the coin. The catalogues don't really have much choice; they file the coin under the date that appears on the coin, because anyone who buys one of these coins without knowing the story of their issue will look up "2013" in the catalogue, because that's what the coin actually says.

When Krause actually know that a coin was issued in a different year, they will usually put a "Note" explaining the actual year of issue. For example, here's one of the "frozen date" coins of Ethiopia; the coin is dated 1936 in the Ethiopian calendar, which equates to AD 1943-44, but you can see the note explaining they were actually struck anywhere between 1944 and 1975. The entry for the Pakistan coin does not have any such note.

The NGC website you linked to above, uses data copied directly out of the Krause catalogues. They usually copy over all the Notes about a coin as well. So the information that appears there on the NGC page should be exactly the same as the information that appears in the Krause catalogue. Since there is no note explaining the coin was actually issued in 2015, it seems likely to me that Krause does not know the actual year of issue.

Yes the #s are assigned by the editors.

They don't always know of every new coin.

I actually emailed the new editor and she had #s assigned for the 2014 Commemorative Kennedy halves in about 2 months. THis was after about six fruitless attempts to contact them through their customer service page.

I stopped adding KM numbers to my world coins in 2X2s. Now I'm regretting that decision because it would make them easier to look up...

That is a step in the right direction.

Thank you for the followup.

And Congratulations!

Excellent!
