✅ SOLVED Pewter color button ID help

[cmthunder]

Found this button at 1860 home site in woods in Cecil Maryland.
What kind of button and date range is this large button?
Thanks for any I’d help!

That looks like a mid to late 18th century tombac button, a metal alloy very popular back then.

Thanks Smokey never found a tombac this big before.
