Well, new things just keep popping up. Look at these cute Woolworths Spares MOP buttons, and compare them with the plastic ‘Tecpearl’. Tecpearl were meant to be so like real MOP that “only an oyster can tell the difference”. A slight exaggeration?
This button is special. It is made from a mint condition silver 1910 King Edward VII threepence. I wondered at that, as it is illegal to deface/alter current Australian currency. However, this was the year the King died. I presume some coins were not released and so could legitimately be made into commemorative waistcoat buttons.
