Possible early 1800s flat button, need help

[40 Rounds]

Hey everyone. I found this small flat button in an area that is predominantly known for late 1800s to the present day as it’s an old park. Prior to being a park it was a private property/farm that dates back to the 1840s. The family that owned the property sold it to the city which then turned it into a park in the 1890s. I have never found a flat button before as the area I am in is mostly city and suburbs with a lot of disturbed ground. I haven’t been able to reveal any kind of back mark but it looks like it had a silver wash on it that is now peeling off. Anyway I was hoping some of guys with more experience with these buttons would let me know what you think. Is it early 1800s to 1840s or possibly just a 1900 era button. Any thoughts would be appreciated. The Mercury dime is for scale.

Yes as shown on the chart, it's most likely from the early 1800s.

Looks like early 1800s to me. Amazing the little things a metal detector can find!
