✅ SOLVED Found a old button the a 1850’s Park

NOT SOLVED!!!! Can anyone tell me what kind of button this may be. I thinking round button it was deep and had white patina on it so I thought lead, the I realized that it had green underneath so is that brass? And if it is brass how should I clean it up to see if if it has any under markings with lemon juice? Thanks for the help.

Like could this be it?

I agree...
From your pictures it looks like a Ball Button.

Very cool! I have never found one of those.

Maybe a Victorian shoe or glove button?
