Yep, dual-denomination coins like that are found in quite a few series - most commonly in cases just like New Zealand's, where the currency was changed and "intermediate" coins with both old and new units were included on the coin. The Rhodesian ones are probably the best example - in the 1964 series, the 5 cents, 10 cents, 20 cents and 25 cents all had their predecimal equivalents (6d, 1/-, 2/- and 2/6 respectively) included on the coins.
There are a couple of instances where the two denominations were merely different ways of saying the same thing - "One Florin - Two Shillings" on the Australian King George V florins is an excellent local example of this.
There are also a very few examples where two completely different monetary systems were referred to. There are only two that come to mind at the moment, though undoubtedly there are others: The Moldavia & Wallachia coins for the Russian protectorate in the 1700's are dual-denominated in kopeks (Russian currency) and para (Turkish currency); and the "habitant tokens" of Lower Canada (Quebec) in the mid-1800's were dual-denominated in sous (French currency) and pence (English currency).
