Revolutionary war button? Need ID.

[diabolicalbeans]

I found this button pretty deep in an old cellar hole, I think it might be from the revolutionary war, I can very faintly make out some writing on it I rinsed it in water and it seems like it rinsed off a lot of the patina unfortunately. Does anybody have an id?

Looks like a flat button from the 1800's based on the back-mark.

Erik in NJ is correct. That style button started to be made after 1800 and yours probably 1820-1840 or so.
