I’ve never purchased buttons of any kind before so this is new territory to me. There are three large buttons and four smaller ones. I believe the larger ones were for the shirt and the smaller for the cuff of a blouse.
Buttons are cool. The old ones are very collectible. Most of the buttons I see are all silver, or with a very small (snake eye) style stone. Your buttons are unique, they definitely don’t look new. I would guess sometime after 1990. Small ones $60 - $90, larger $80 - $110.
