It seems that mail from the USA to Hanover during the 1860s is far less common than other German States. Of course, my perspective is skewed because I focus on the 24 cent stamp. That means I pay less attention to unpaid or stampless items and I am less likely to view items via Bremen or Hamburg. Even so, I am starting a new thread to show a USA to Hannover cover - so maybe I am not far off?
Here is a Prussian Closed Mail item showing the double 28 cent rate for an item weighing more than 1/2 ounce and no more than 1 ounce. 14 cents are passed to the Prussian mails who cover the cost of the Belgian transit (4 cents).
I am a little surprised by the red 1/2 on the back. Would this be a delivery charge collected at that point or is this 1/2 silbergroschen passed on?
I hope everyone has a fine day.
