Set of 4, Vintage Sterling Silver Button Covers, Same Flower on Each 3/4" #MV-49

Finely detailed artwork, beautiful condition, classic glowing Sterling sheen, we are told vintage 925 Sterling Silver, probably 1970's. Clearly they have been carefully stored; they seem barely used.  We are told the tops are Sterling and the base and hinged closures are stainless steel.  The flower centers have a tiny diamond and circles design - they really add a lot in our opinion. Two have a slightly stronger design and the other two are a bit lighter; the lighter ones' designs are black, just finer. Probably not noticeable to most people? We only have this one set, of four.
