Kccj76, there seems to be nearly endless variations in the "Quality Rating" backmarks on that type of brass button. According to the various books on antique buttons, that quality-rating system was originally created in Britain in the very-early 1800s, and at first it was used with "seriousness." But that system quickly devolved into meaninglessness, as the button-manufacturers competed by using ever-more-superlative terms. (Such as fine, superfine, treble superfine, rich gilt, extra-rich gilt, etc.) So, the only thing your unusual variation of quality-rating backmark tells us is that your 1-piece brass flatbutton is most probably a British-made one, rather than US-made. Just in case you don't already know... dug-in-America brass 1-piece flatbuttons with "indented" (not "raised") lettering in the backmark date from approximately 1810 into the late-1830s.
