The series started in 1988 and finished in 2005. Only the 1/2 oz proof koalas were made in every year. They were housed in a wooden box with a metalic certificate. The paper covering of the wooden box was silver colored..
I started colecting these 1/2 platinum proof coins, and have the first 3 years, and a few more, but from the 18 pieces series missing least a dozen. If anyone has these later sets with boxes and the metal certificate (see the example), and want to sell them I might be interested to buy them if the price is reasonable. Just let me know what you have and the price.
