I sold a pin (also a spooky from zaccaria!) to the states more than a year ago.
I will send you the email in pm of the person who bought him and you can ask him for details how match it cost to import in the USA.
The shipping from Belgium to USA was 1300 € with special packaging.
I’m sure with boat will we cheaper but off course will take longer.
And a spooky is a more then hard to find pin but I’m Shure you are aware of that
Good luck with the hunt
