I found two coins from an old Ahlstrom Auction 60 lots 201 and 203. Two coins labeled as Penning Magnus Ericson, but not known if Norway or Sweden, dated 1319-1363, on paper sleeve. Please help with identification. Thank you.
I believe the first one is a type which has three crowns forming a triangle, with a letter or symbol in the center (first photo) and a rampant lion on the other side (second photo).
