Sorry, but your button is from later than the Colonial Era. It probably is British-made, but it dates from around 1810 into the 1830s, which is the time-period for brass 1-piece "flatbuttons" dug in America that have their backmark written in indented (not raised) lettering, as we see on yours).
Your button's backmark saying "TREBLE GILT" means triple goldplated, and "STANDARD" was one of the quality-ratings used in the British button-backmarking system. I should mention, the young American button-making industry initially copied the British quality-naming system, using terms such as fine and superfine.
In my first paragraph, I used bold-type to emphasize the importance of your button being dug in America for accurately time-dating it. By the early-1830s, American button-makers had finally become capable of inexpensively mass-producing brass 1-piece flatbuttons, so after that time there was no longer a need for American customers to pay the US Government's expensive Import Tariff (tax) on manufactured goods imported here from other countries.
