Button Backmark Question

[J23]

Hi All-
I found this today on an old house site in Connecticut and I wonder if anyone recognizes this backmark or can date this button? Does anyone know the maker?

The backmark is pretty clean. From outer rim in it has a ring of dots, then alternating stars and what look like wheat and then there is a diamond around the shank. At the bottom of the diamond it "Stand Colr" is written.

Trying to date the site... I believe this is an early 19th century civilian button. Front is blank, edge slightly rounded (almost like a tombac).

Thanks all

Stand Colr Is Just Short For Standard Color. A Common Quality Backmark On Early 1800S Flat Buttons. Some Word Combos Early Button Companies Used Were Gilt,Orange,Standard,Rich ,Treble ,Double... Etc. Some Of These Words Stated How Many Times It Was Gilted In Gold. Example: Gilt For Once,Double For Twice, And Treble For Three Times.
