Assuming no coins have been melted/lost etc, and going by what has been released SO FAR in Series 2, here are the maximum number of sets possible: Series 1 1/2oz: 16,913 (incomplete due to no minting in 08+) Series 1 1oz: 52,267 Series 1 2oz: 6,465 Series 1 10oz: 2,486 (incomplete due to no minting in 08+) Series 1 1/2kg: 785 (incomplete due to no minting 99-03 and 08+) Series 2 1/2oz: 17,114 Series 2 1oz: 300,000 Series 2 2oz: 9,126 Series 2 5oz: 3,005 Series 2 10oz: 3,718 Series 2 1/2kg: 739 (incomplete due to no minting in 11+) Figures from here: http://www.silverlunar.com/p/perth-mint-s1-silver-lunar-mintages.html http://www.silverlunar.com/p/perth-mint-s2-silver-lunar-mintages.html
The 1kg's will be interesting but wont know them until at least 2019. The number of coins minted does not always determine available supply however. If 300k coins are minted for example and are widely distributed, their availability will be greater (and thus lower price) than 300k coins minted that the lions share of which are held by a few dealers / interested parties. The 2012 Dragon is a classic. APMEX, Gainesville and all the US dealers have them priced up at $99 a pop because these select few control the market. But elsewhere the distribution of the Dragons was more widespread at a lower price, hence in Australia you can get them for about $60.
