Speaking of the copper-nickel Bahamas 5-cent type of 1966-70 (KM#3), the Krause
SCWC says: “The obverse of this coin also comes muled with the reverse of a New Zealand 2-cent piece, KM#32. The undated 1967 error is listed as New Zealand KM#33.”
Krause estimates that 50,000 of these mules exist, and prices an AU example like this one at about $17.
How many of these mules actually exist is unknown, however. All of the error coins were shipped to New Zealand, and many entered circulation. Only after people actually began using them was the error discovered. The authorities immediately began to withdraw the coins, with some success. And many of the new coins, of course, remained unissued.
But then the NZ authorities—at some later date—also permitted many of the (1967) “Bahamas Mules” to be given out to the public for promotional purposes. Whether the coins were distributed beyond the country’s borders I don’t know. Prices for the coin did fall for a time, but then began to climb again.
The (1967) “Bahamas-New Zealand 2-cent?” It remains one of the best known “mules” in the world of coin-collecting.
