Here is a list of all confirmed 1990 Nintendo World Championships Grey Cartridge
LIST REMOVED UNTIL FAKER IS CAUGHT SELLING.
NOTE: The three "Confirmed with No Photos" copies are considered known to exist because they were previously discussed on NintendoAge. Photos have since been removed from the internet and no known photos survived.
The one rumored copy is from a very reliable source. I do not have any photos to prove it exists, but I am very confident that this source has no reason to lie. They wish to remain anonymous, but do not mind the number of their cartridge to be known.
All cartridges in green or yellow are confirmed to exist. The 1 cartridge with a blurry photo is too blurry to make out the number, but its number is known because of NintendoAge discussion. It may as well be considered "Confirmed with No Photo" since the blurry photo is the only one that I could find.
It is my solemn duty not to track owners, or sales data.
IF YOU OWN A COPY AND WOULD LIKE TO KEEP ITS NUMBER A SECRET, PLEASE ALLOW ME TO KEEP YOUR SECRET SAFE. There may, or may not be more copies in my archives not on the above list.
