Here is the little I’ve uncovered. Roger Berry Pty. Ltd. was incorporated in New South Wales on 18/07/1946. From at least 1947 until 1956 they advertised in newspapers and magazines. Roger Berry Pty. Ltd. wound up on 21/1/1975.
It appears that Roger Berry was a wholesale distributor of buttons, slides, dress accessories and other haberdashery. Perhaps they distributed and/or bought out Coronet branded buttons??
I purchased these beautiful samples from Kate Boulton of Buttonmania, Swanson St, Melbourne. Coronet buttons were marketed as “Buttons of the Moment” and also “Artistic Accessories”.
Robyn Greenwell (Button Broker) started my collection of these plastic and metal Disney buttons (below). She has seen a complete card of metal Disney’s with the Coronet logo. We don’t know whether the plastic Disney buttons were Coronet also, but they do originate from Australia and are considered hard to get buttons by collectors of novelty buttons in America.
Notice that the metal buttons are further mounted in a plastic surround to make a more fancy button (the white Donalds). The Donalds also show variation in the painted finish, as one has an orange bill whilst the other has orange. This kind of variation is due to the painting being done by hand. The variation in amount of detailing, as well and the changing type of plastic indicates that these buttons were made over a period of time. Hand painting was labour intensive, and therefore became too expensive.
The buttons below are Carol’s.
