Aidan is your best bet on this forum, he is very knowledgeable in the area of British Commonwealth coins.
I think there is a forum here for other country coins. I know on PCGS web site there is a foreign coin forum. Good luck.
Beshergh,I am very out of touch as far as most British Commonwealth countries' issues go.We will be getting a new series of coins released over here in New Zealand.Here's a link; www.newcoins.govt.nz . Zimbabwe's banknote issues are getting bigger in terms of denomination range,as the value of the Zimbabwean Dollar plummets further & further down the pan.The highest denomination is currently a $100,000 Bearer Cheque.I wouldn't be too surprised if higher & higher denominations are going to be issued. Ireland,although it is not currently a member of the British Commonwealth,has issued some very attractive coins which are of interest to British Commonwealth coin collectors.You can find some information about Irish Euro coins here; www.centralbank.ie .
