Thanks for the great info Litotes!
That's really helpful towards understanding these coins.
KT, this globe and the three little crowns somehow reminded me of a bee hive and 3 bees.
More seriously, checking the history behind the three crowns, I read that:
"Albrekt av Mecklenburg was proclaimed King of Sweden and officially crowned on February 18, 1364. The coronation took place at the Stones of Mora. A fragment still remains of the stone comemorating the occasion, the Three Crowns stone. This is the earliest known example of the use of the three crowns as a national symbol for Sweden."
