12pc Antique Metal Victorian Mixed Twinkle Buttons B711

You are buying the 12 buttons shown in the photo.  I am calling these twinkle buttons. They have some type of filigree front and something reflective below it.

Timeframe: Late 19th Century (c. 1870s–1890s)
Mixed metal, decorative stamped buttons like these reached the height of their popularity during the Late Victorian Era (roughly 1870 to 1900). Prior to this period, elaborate buttons were largely a sign of high wealth and primarily featured on men's coats.   By the late 1800s, industrial stamping techniques made decorative brass and steel buttons accessible and trendy for women's fashion, particularly for tailored jackets, dresses, and cloaks
