I heard somewhere the certs of authenticity were valued at around $5-$10. In the scheme of it all, it's a big fat 'meh'. Its the gold, baby..the gold! ps.. sorry couldn't help on the value of gold roosters.
i'd say US$3495, per here: http://www.apmex.com/Product/61523/...d_Year_of_the_Rooster_Lunar_Set_Series_1.aspx some of the other animals go for more. there are quite a few for sale on this page: http://www.apmex.com/Category/515/Australian_Gold_LunarSeries_1___1996_2007.aspx
Welll Here I was thinking French 20F coins. If they are Perth Mint Lunar Roosters then maybe the COA is worth a few cents.
I saw some Perth mints for $3750. I wanted them straight away but my wife looked at me and said.... Bang for buck silver..... That's why were here and sure enough she don again.
