Hello all numismatic friends. Here on Numista there are two types of 5 öre 1910. In Sweden its considered that a 1910 with large base on mintmark are fakes. These fakes were made of 1919 or 1940, I myself have come across one example, luck that I hadnt paid more than scrap for a pile of coins 🤣.
link to the article below, its in Swedish but today there are lot of AI help to get🫣.
