Keeping track of circulated coins

[kallikak]

Hi,

I endeavour to keep my collection as a basic type-set of Australian coins, but it's quite frustrating given the rate at which the mints produce commemorative coins.  I am only interested in coins released into circulation - so I don't bother with most of these (e.g. the many Anzac variants, the motorsport coins, the endless alphabet releases), but every time a new coin is announced - e.g. the Indigenous Languages 50c or the Repatriation $2, I need to try and find out if they are going to be released or not.

Can anyone point me to a reference website or similar that makes it easy to know if it's a circulation coin or not?

Thanks

Ken
