Hello,
I've recently acquired some of Sweden ¼ Öre - Kristina and am trying to understand a classification. I found the 4 pages for such coins on Numista, but one of them seems to be duplicate with a non-existing KM#.
https://en.numista.com/catalogue/pieces22663.html - seems to be the same coin as N#64182, but with a wrong KM#. Years are the same, but with an info about unconfirmed 1646.
I think the N# 22663 shall be deleted, all the owners shall be moved to N# 64182
