KM Numbers For Foreign Coins

2 posts in this topic

Why do only some NGC inserts list the KM numbers for foreign coins? I noticed several new NGC slabs and it seemed like maybe half of them had the KM number while the other half just had the standard information.


There seemed to be no real reason for the ones that did/didn't have the KM number.


For example, there was one coin that did NOT list the KM number. However, there are two varieties listed in the KM World Coins book that had the same date and mint mark. Another coin that had no varieties had the KM number. Seems to make no sense. confused.gifconfused.gifconfused.gif

NGC does use KM numbers on world coins when there is more than one type or variety of a particular date. If you received a coin that has multiple varities and it does not have a KM or other reference number please send it to us and it will be added. KM numbers on all world coins is a relatively new creation. A few years ago Krause used Y#s, C#s or Dav#s depending on the era. We are in the processs of switching over to KM numbers as most collectors in the US have easy access to these publications. It's easier for NGC as well to have one source of refernce numbers.
