This is what a banknote looked like in 1806

Kind of like a traveler’s check? Where the bearer signs on receipt? And I wonder, did the bank president and the chief cashier sign every note? Or were they printed on?
This note looks a bit like one of those business cards that companies used to give employees, with space to write their name. In this case, “Detroit Bank” and “Five Dollars” looks like it’s printed in. Here‘s a closer look.
I can’t find any reference to the Detroit Bank in the early 1800s, either. Detroit wasn’t made capital of Michigan until 1805, and wasn’t even incorporated as a city until 1815. But it looks like it had a legitimate bank, nonetheless.
