I suspect that too. I haven't seen it in the decimal coins of the UK. I am sure someone here is able to tell me if this is common, uncommon or rare. I know there are some very experienced Australian collectors here
Common or not, it's nice to have an error Australian coin here, so far away from its' homeland:)
