 The first instance occurred in 1967, when the two cent coin was accidentally minted with the obverse of the Bahamian five cent coin.Subsequent examples include a New Zealand 1981 5c obverse muled with a Canadian 10c reverse and a 1985 50c obverse muled with a Canadian $1, both of which are extremely rare.Another example occurred in 2000, with ten known instances of the commemorative $5 coin found in uncirculated sets.
