I picked up a pair of circulated 1967 10 cents from my weekly grocery shopping and there is a surprise to it. One is definately a 1967 Aussie 10 cent and the other happened to be a Kiwi 10 cents!
What's more interesting the Kiwi coin has dual denomination, 10 and 1 shilling on the reverse. I don't think I'll pull out any more interesting coins than that!
