First Old Imperial Standard button found on my property. Help dating please.

Hey diggers,
I just found this button the other day
detecting my property. It had an old 1850
school house on it. But this button seems older than the school house. Thanks all HH

I would guess that button is early 1800’a to mid 1800’s. Congrats

I'm no expert on buttons but if I remember correctly the consensus on these is that they are from the first haft of the 19th century.
