Mintage of 5058, same diameter as the 1kg coins but half as thick. I'm not entirely sure what's a fair price for this one since they hardly ever come up for sale. There's one on eBay Germany for around AUD$665 and some listed on APMEX for ~AUD$1060. Make an offer via PM. I won't be insulted, but I might decline. If you've bought or sold one recently and are happy to (privately) let me know what the price was it would be much appreciated.
