These white metal buttons are all very heavy and chunky. They appear to me to be pewter but I don’t really know.
One is a flowery design and another a swirly pattern. The flower one is backmarked LANDICO. The middle one is very deep and an unusual shape and pattern.
They all seem crudely made as seen by the backs. I have bought them in opp shops in the last 10 – 12 years and don’t know their age
