Strange flag pin, ID help

[ugotit22]

Dug this small pin about an hr ago in a park. Was pretty deep down too. Its about the size of a dime, and is white with e blue circle in the center with, three crowns in the circle. Any idea what its from?
Thanks

3 Crowns is the old Swedish Coat of Arms. Three Crowns - Wikipedia, the free encyclopedia

Some of those images look really close.
