The 1c/10c is pretty cool--something I thought impossible. How did that occur?  |

The only genuine mule I have is the New Zealand / Bahama Islands 2 cent in uncirculated. Most are of this condition. About 80,000 were produced. The two dies were mismatched, and the coins produced were only discovered after issue. This is the result of the British Royal Mint executing coinage contracts for a number of countries at the same time. Incidentally, you can't have a daddy mule and mummy mule produce a baby mule. The genetics won't allow it. Same with different species of plants, eg. nectarines. So how do different species evolve from earlier types? |

Hybridization producing fertile offspring is common among both plants and animals. Hamadryas baboons interbreed in the wild with neighboring savannah baboons. Different species of gibbons interbreed in the wild producing fertile hybrids. The red wolf is a hybrid species derived from the gray wolf and the coyote. Hybridization is a common mode of speciation among plants. It is less common among vertebrates, but it does happen. Evolution typically proceeds as the result of natural selection filtering random mutations and genetic rearrangements that yield superior phenotypes.

Hybrid plants are frequently fertile. Maize probably originated as a hybrid and subsequently domesticated. Wolphins (a cross between a dolphin and a false killer whale) are fertile, as are Beefalo (domestic cow/bison cross) and several snake hybrids. Even the classic example of the sterile hybrid - the mule - is occasionally fertile. There are a number of documented examples of a female mule (and at least one of a female hinny) successfully having offspring with a male horse or donkey, though there are no recorded cases of fertile male mules.
I don't know of any documented cases of mule coins reproducing, which probably contributes to their scarcity.

The dime die was installed in the cent press and the mule is struck on a cent planchet.
There has also been claimed a different cent dime mule struck on a dime planchet WITH a reeded edge which is impossible. (To get the reeded edge it would have to be struck inside the dime collar and a cent die would not fit inside the collar. Well maybe not. Since the collar is mounted on heavy springs it might be able to force the collar down far enough to make contact with the planchet. Probably destroyed the cent die within just a couple of strikes though.)
