There are two versions of the 13th Century coin out of Cook Islands in 1997: N#171605 and N#171600.
When I look at my 2019 Standard Catalog of World Coins it appears the KM numbers in Numista are swapped from the numbers in Krause. The image here is captured from my Krause catalog. The difference in the pages are whether the text in the lower right of the reverse is in a box or just on top of the image.
