Button Information please

Just trying to date button? Front is slick. Thanks

My best guess is 1820s-1840s

Perhaps you can confirm, but it looks to say 'BEST FINISH / LONDON'.

Backmarks like that typically date from the late18th century to the mid-19th century (c. 1790s–1850s).

It may read BEST GILT. If so, a "Best Gilt London" mark typically indicates a high-quality, early 19th-century copper-alloy flat button manufactured in Britain. These historical metal buttons, frequently excavated by detectorists and archaeologists, used actual gold brushed onto the brass. They gained popularity between 1800 and the 1840s as fashionable garments for dandy and gentlemen's coats.
