Those are contemporary issues, produced by the Kingdom of Northshield, a Society for Creative Anachronism organization. They commemorate the reigns of respective Kings and their consorts. The Northshield moneyer, Bartel Fitz Neel (who engraves and hand strikes the coins) sent me those and some of other previous reigns, tournaments and site tokens. Amazingly cool stuff. Most have a mintage of under 300, but he also sent me a test strike for a planned striking of 10,000 pieces at the upcoming Pennsic Wars this summer. They engraved seven obverse and 5 reverse dies for this immense project.
